Recommended: Development in science during the Renaissance period

Throughout the ages, patterns of inheritance have always been studied. People have always been curious about what causes the appearance of certain traits in individuals. However, by the time the 21st century commenced, science found that the answers to these questions can be found in each cell of the body. Genes. But what are genes truly? Who were the scientists who contributed towards their discovery? What are the recent advancements in the field of genetics, and what does the future hold for this field? 1. The Past To understand the functioning of genes and even the structure of genes, it is essential to know the history of genes, and past assumptions of hereditary. Greek theories. Like in any other field of knowledge, the Greek philosophers have left their mark on the history of genetics. Pythagoras proposed that the male parent provided the material that determined the traits inherited; however, Empodocles stated that both parents played an equal role in the transmission of genes since many children possessed the same traits of their mother. The father of medicine, Hippocrates, put forth the theory of pangenesis. He believed that different parts of the body produced traits that were transferred during conception. Aristotle disproved the theory of pangenesis by presenting evidence that parents who had lost limbs often produced healthy offspring. In addition to this, Aristotle was the first to propose the idea that traits were not affected by external circumstances, humors, or elements (Freedman 10-13). The renaissance. As one may know, the renaissance was a period between the 1400s-1700s where great advancements in science occured.

    Since the completion of the Human Genome Project in 2003, University of Utah biology researcher Riddhita Chakraborty explains how scientists have been able to “read” a person’s entire genetic makeup (1). Genes are sequences of DNA that will determine characteristics like height, eye color, and hair color, just to name a few (1). Finding specific genes for each characteristic, despite the fact there are nearly 23,000 per person, seems like it would be a relatively simple process given today’s advanced technology. However, according to David Epstein, author of The Sports Gene, our genes appear to be far more complex than originally believed (24). As scientists have delved deeper into human genetics, the idea of finding one simple gene that correlates to a specific characteristic appears less and less realistic. For something even as b...

  • Reproduction Research Paper

    The human body is made up of millions of cells, each containing heritable information in the form of DNA. This DNA contains genetic information known as genes which can be passed down from one generation to the next, and is expressed as the numerous traits we see in various organisms today. Genes can therefore be seen as the unit of inheritance from parent to offspring (Campbell undated). In the following essay I will discuss the reproductive process and how the passing of genes leads to offspring having similarities to their parents. In addition I will look at the two methods of reproduction and how each leads to similar or different traits expressed in the offspring, as well as the evolutionary significance of genetic variation within a population.

  • Genetics In Offspring

    Genetics is the study of heredity and the variation of characteristics inherited from parent to child through generations. Genetics are passed down through chromosomes in DNA which are located in every cell of the body. Each cell contains 46 chromosomes (23 pairs) including the X and Y chromosomes. The only exception to this are the sex cells (sperm and egg) which have 23 chromosomes. Each chromosome carries genes for a certain trait which will be inherited to the offspring. When a new organism is fertilised through intercourse, the 23 chromosomes from the father’s sperm combine with the genes from the mother’s egg. Each pair of genes will find each other and determine which trait will be expressed in the offspring.

    Gregor Mendel was an Austrian monk who revolutionized our understanding and perception of genetics. Mendel’s experiments in his monastery garden provided future geneticists with the basic principles of hereditary through the experimentation in both hybrid and pure bred pea plants, which he found to follow specific patterns in their offspring. The choice to use peas was because of their distinct varieties and their ability to produce offspring quickly and the ability to easily regulate fertilization simply with the use of a paintbrush. When conducting these experiments Before Mendel Pea Plant Experimentation it was commonly accepted that a child’s genetic traits were simply half from the mother and half from the father. This evidence was supported by experiments were generally conducted over a short period of time resulting in skewed and unreliable data, whereas Mendel’s experiments were conducted over an eight year period involving tens of thousands of plants. Two of Mendel’s traits that he focused on were the texture of the seed pod. E.g. smooth and round or wrinkled. In the first generation of these plants 100% of the pea plants possessed the Smooth and round texture. On the second generation of the pea plants of every 4 pea plants 3 posessed the smooth trait and a singular pea plant produced wrinkled seeds. Upon the review of his results Mendel concluded that characteristics could be expressed through dominant and recessive traits. The Dominant trait masks or completely covers the recessive, whereas a recessive gene is an allele that is only present in a homozygous genotype. Through Mendel’s experiments he proposed three principles of inheritance, whether you are looking at humans or pea plants, the apparent genetic traits t...

    When one thinks of biology, one of the first topics that might come to mind is Mendelian genetics and the concept of genetic inheritance. In the 1800s, Gregor Mendel pioneered many scientific breakthroughs in the area of genetics by exploring specific genes, also known as units of inherited traits, being passed down to offspring. Mendel achieved this by crossing, also known as breeding, pea plants and observing seven characteristics among generations of offspring. These seven characteristics were plant height, pod shape and color, seed shape and color, as well as flower position and color. By doing this, he realized that only two different traits of each characteristic was shown.

The science of and our current understanding of genetics has come a long way since Gregor Mendel’s pea experiments. Who is Gregor Mendel? Gregor Mendel is often regarded as the forefather to the genetics that we know today. If it was not for Gregor Mendel’s early pioneering in a subject that was practically rejected during that time period, who knows where genetics would be today and who knows what we would know.1,2

    Genetic engineering is the gateway into an advanced realm of medicine. A realm where disease can be eradicated. A realm where parents can decide what attributes they want in their offspring. For genetic engineering to reach this point, it will need to become more of an acceptable practice, especially its use in fetuses and infants. These so called “designer babies” are the key for this progression (Britt). Society must just accept and adapt to these medical developments in order for the next step in human evolution to commence.
