I am researching Klinefelter syndrome. It is a chromosomal disorder that affects only males, and the disorder is neither dominant or recessive. If you or anyone else in your family has had this disorder, klinefelter syndrome, and you would like to find out if your child will be having it, you will need to let a doctor know about his past health, do a physical exam, or order a chromosome test called karyotype. There are effects that come with klinefelter, some noticeable effects are sparse hair, enlarged breasts, and wide hips. A mens voices will not be as deep, and they will not be able to father children.
Sometimes men will also have problems with their language or with speaking, and problems with learning as well. They can be given testosterone,
with women is apprehensive, and causes him to be withdrawn from society as a whole.
Both male and female brains are different and extends into a difference of what they can
Duane Syndrome is an inherited unusual type of strabismus (squint) most often described by the incapability of the eye(s) to move inwards, outwards individually or together. This was first reported via ophthalmologists Jakob Stilling in 1887 and also Siegmund Türk in 1896. The syndrome was named after Alexander Duane, who explained the disorder more specifically in 1905. The syndrome is described as a miswiring of the eye muscles, causing eye muscles to tighten when they don’t need to and other eye muscles not to tighten when they need to. Very often patients get the syndrome by the age of 10 and it is more common in females (60% of the cases) than males (40% of the cases). Although the eye is usually the abnormality associated with Duane Syndrome, there are other bodily functions that can be affected. Duane syndrome cannot be cured, because the cranial nerve is missing and it cannot be replaced. The gene known as “SALL4” has been associated as a cause of this condition.
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
also possibly be a result of societal pressures on men not to admit to the symptoms (Wehrenberg
18. a) Explain the process of nondisjunction can result in an individual with Klinefelter syndrome. Create a diagram showing the disjunction occurring in the mother to help explain your answer. Individuals with Klinefelter syndrome have XXY chromosomes, and can occur when during the prophase of meiosis I, in females there is nondisjunction of X chromosomes. This results in a male with trisomy. One egg can have no X chromosomes and the other could receive both X chromosomes.
disease makes him insecure and scared to speak up for himself. It makes it hard for relationships
Sex-linked disorders only affect males and are passed down through female carriers. A boy inherits the disorder when he receives an X chromosome with a mutated dystrophin gene (the genetic cause) from his mother. The dystrophin gene is the largest gene found in nature and was identified through a positional cloning approach. It's a highly complex gene, a large rod-like cytoskeletal protein which is found at the inner surface of muscle fibers. (www.ncbi.nlm.nih.gov)
The desire to have a "normal" child is held by every parent and only now are we beginning to have the ability to select for that child. In preparation to receiving genetic testing, the parents are required to meet with a genetic counselor. A detailed description of the testing methods are reviewed with the couple as well as the risks which are involved with each. Upon an understanding of the procedures, the counselor discusses the many possible outcomes which could be the result of the diagnosis. Finally, before any tests are performed, anxieties from either of the parents are addressed as well as the psychological well-being of the parents.
A Karyotype is when you cut out individual chromosomes from a picture and rearrange them. There are matching pairs of chromosomes these are called homologous pairs. Each pair is given a number. One of each pair came from the mother and one of each pair came from the father. The pairs can be distinguished as each pair has a distinctive banding pattern when stained. There are two sex chromosomes and the rest are called autosomes. In most karyotype the sex cells are kept to one side so that the sex can be seen easily. In females they have two X chromosomes and in the males they have an X and a Y chromosome. The Y chromosome has a portion missing and is therefore smaller then the X chromosome.
While 'male menopause' has provided both sexes a variety of jokes and frustration, there are researchers and scientists studying the alleged condition with great seriousness. Those who support the existence of male menopause feel strongly that its affects on the male mind and body should be regarded with the same credence that society attributes to the female menopause.
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.
Men and women are more different than one can imagine. Though the main difference is in physical appearance, another difference is their sense of communication. Women appear to talk more than males, but like to keep their conversations more private. Males, on the other hand, will talk less, but do not mind their conversations being more public. This is just one of many examples of men and women being completely opposite of one another in terms of communication. Each gender has their own expectations of the opposite. These expectations are not usually met due to communication differences, which leads to criticisms such as, “Men do not listen” or “Women will never understand” to form. The most common assumption for why expectations are not met
For this reason, one could argue that while the school system may exacerbate the issue, male underachievement stems from many other disparate root causes which include social/environmental factors, intrinsic issues and family
