Apart from the obvious biological differences between Men and women we differ in numerous ways, some of which we aren't even conscious of. The way we look, the way behave is all a part of our DNA. We have different genes, our brains are wired differently and we have different hormones. We all know that women have two “X” chromosomes and men have one “X” and one “Y” chromosome. The X and Y chromosomes determine a person’s sex. Chromosomes contain the set of instructions to create living being. The male Y chromosome and female X chromosome are different in size and vary in the number of working genes. The X chromosome can contain more than 1,000 working genes, while the Y has less than 100. There have been several studies done on the inactive X chromosome in women. "Our study shows that the inactive X in women is not as silent as we thought," said Laura Carrel, Ph.D., assistant professor of biochemistry and molecular biology, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center. "The effects of these genes from the inactive X chromosome could explain some of the differences between men and women that aren't attributable to sex hormones." There was a study published in the Journal of Nature in March 2005 that discussed the in- active X chromosomes in males. The study said that having two active copies of the gene can matter a lot, or very little. "Although we've shown sex-specific differences, the clinical implications remain unexplored," Carrel said. "We can, however, conclude that these differences should be recognized as potential factors for explaining normal differences between the sexes but also gender differences in how certain diseases are manifested, progress and respond to... ... middle of paper ... ...y more alike than we might think. We all have 46 chromosomes in 23 pairs and only one chromosome separates us from being male or female. We both share some of the same hormones. So are we really that different?

Genetic disorders can be caused by many of the 46 chromosomes in human cells. This specific disorder is linked to a mutation in the long arm of the X, or 23rd chromosome. The mutation is recessive, meaning a normal X chromosome can hide it. Females have two X chromosomes allowing them to hide the mutated recessive one, making them a carrier of the gene, while males only have one X chromosome, meaning that they are unable to hide the mutation and they become effected by the disease. Therefore if a male carries the gene, he is affected because he has no way of dominating the recessive gene, but if a female carries it, she is only a carrier and has a 50/50 chance of passing it on to her baby. This may seem like a high probability however, only one in every fifty thousand male births will have this immunodeficiency disease.
The Duchenne gene has been located on the short arm of the X chromosome. This means that Duchenne muscular dystrophy is inherited as an X-linked recessive disease. Females have two X chromosomes, while males have one X chromosome and one Y chromosome. Therefore, in females, a normal X...
Turner’s affects the second X chromosome in a chromosome pair. This X is either incomplete or missing completely, which causes a decrease in fetal development and also a decrease in the development after birth. Since Turner’s affects the second X chromosome, this means that Turner’s only affects females. However, females of a certain race, nationality or those who live in a certain region of the world have the same risk of having Turner’s. One in every 2000 to 2500 baby girls are born with Turner’s, according to the National Health Service in the United Kingdom. Normally if a baby is conceived with an X chromosome missing, the body will naturally abort the baby, which is a miscarriage. Turner’s is usually the cause of almost 10% of miscarriages in the first trimester.
Both of these methods can help determine and eliminate genetic disorders, as certain conditions can be screened out using these technologies. As discussed in Meseguer et al., more than 300 diseases have been related to sexual chromosomes till date. Case studies also argue the important role of these methods in family balancing for varied family dynamics who aim to compensate their family with a representation of the other sex (Meseguer et al., 2002). Critics have also mentioned that with an increase in demand, these methods could become more economical and widely available, including to couples who may need it due to medical
This absence of part or all of the second X chromosome means that one important gene known as the SHOX gene is missing.
Connell: Chapters 4 “Sex Differences & Gendered Bodies”: I found this entire chapter quite intriguing, but I really appreciate the way that Connell approaches the ways in which males and females differ and yet she also points out how there is no significant difference in brain anatomy and function between sexes. I found the statement by neuroscientist Lesley Rogers incredibly interesting, she states, “The brain does not choose neatly to be wither a female or a male type. In any aspect of brain function that we can measure there is considerable overlap between females and males” (p.52). This statement when paired with information about the affect social processes have on the body it is mind boggling to realize, as Connell states, “biology bends to the hurricane of social discipline” (p.55). It is unnerving to think that I am merely a product of my society. Not only has society shaped my beliefs, values, manners and religion, but it has also shaped my physical body? If I understand this correctly, it is incredibly disturbing.

During the early years of psychological research, many believed the brain of a male and female was different as their physical appearance in selected areas. The most popular argument was that females had smaller heads and smaller brains than males that brain size was a direct indicator of intelligence and that women must therefore be less intelligent than men. (Hyde, 1990, p.56) The argument overlooked the fact that brain size correlates with the size of the body. Helen Thompson Woolley dismissed the argument on brain size stating, “It is now a generally accepted belief that the smaller gross weight of the female brain has no significance other than that of the smaller average size of the female.” (Hyde, 1990, p.57) During these years, you could only find a meager amount of research using actual psychological methods to determine gender differences.
Gender is not about the biological differences between men and women but rather the behavioral, cultural and psychological traits typically associated with one sex. Gender is socially constructed meaning it 's culturally specific, it 's learned and shared through gender socialization. What it means to be a woman or man is going to differ based on the culture, geographical location, and time. What it meant to be a woman in the US in the 19th century is different than what it means to be a woman in the 21st century. As cultures evolve over time so are the ideals of what it means to be man or woman.
Gender is determined by the sex chromosomes, XX produces a female, and XY produces a male. Males are produced by the action of the SRY gene on the Y chromosome, which contains the code necessary to cause the indifferent gonads to develop as testes (1). In turn the testes secrete two kinds of hormones, the anti-Mullerian hormone and testosterone, which instruct the body to develop in a masculine fashion (1). The presence of androgens during the development of the embryo results in a male while their absence results by default in a female. Hence the dictum "Nature's impulse is to create a female" (1). The genetic sex (whether the individual is XX or XY) determines the gonadal sex (whether there are ovaries or testis), which through hormonal secretions determines the phenotypic sex. Sexual differentiation is not drive...
He published a comprehensive medical description of the syndrome. It was not until 1959, that it became clear the syndrome was due to lack of sex chromosome material. Turner's Syndrome is a rare chromosomal disorder that affects one in approximately 2,500 females. Females normally have two X-chromosomes. However, in those with Turner's Syndrome, one X chromosome is absent or is damaged.
The same concept was expressed by Edward O. Wilson (1992), father of sociobiology at Harvard University. According to him, females tend to be better equipped in characteristics like verbal and social skills, security needs and empathy than their counterpart. In the other, Males tend to be better in spatial ...
It is proven that the male and female brains differ, but can one prove that it affects the behavior? Many scientists would agree that ones behavior is determined by his/her gender. Although others are convinced that social conditioning is the cause for the differences between the male and female, it is very unlikely that biological differences play no role in behavior. The male and female brains differ not only by how they work, but also on the size. For example, Natalie Angier and Kenneth Chang, neuroscientists, have shown that the women’s brain is about 10 percent smaller than the male’s, on average, even after accounting for women’s comparatively smaller body size. Three brain differences that affect ones behavior are the limbic size, the corpus collosum size, and the amount of gray and white matter.
Sex and gender are terms that are mixed up from day to day and seen as similarities rather than differences. Sex is what distinguishes people from being either male or female. It is the natural or biological variation between males and females (Browne, 1998). Some of these variations are genital, body hair, and internal and external organs. It is the make-up of chromosomes, men have one X and one Y chromosome and women have two X chromosomes, which are responsible for primary characteristics (Fulcher and Scott, 2003).
Males and females are generally distinguished from their nature and their abilities to perform certain jobs. Females are addicted to fashion but males are not addicted to this materialistic world. Males and females both have their own ways of entertaining themselves. Males are generally considered to be strong according to strength. Thus, both males and females are differentiated using the terms masculinity and femininity.
