Free Genetics Essay

1. Many genes only have a few possible alleles. For example, humans only have a few eye colors and only four blood types. How can DNA tests definitively identify individuals when many men have brown eyes or type A blood?

In simplest terms, we all consume food. Therefore, we are all most likely also consuming Genetically Modified Organisms or GMOs, whether we are aware of it or not.

Did you know that 80% of the food packages sold in the United States have GMOs in them? Its true! Imagine going to the store simply for a can of beans, or even just a chocolate bar. There may be a good chance that the food product selected contains GMOs.

---If given traits and parents, be able to use a Punnett square or patterns to predict the probability of offspring for a given cross and express it as a fraction, percent, or ratio.---

A) Describe the essential features of TWO of the procedures/techniques below. For each of the procedures/techniques you describe, explain how its application contributes to understanding genetics.

2. Choose one of the research questions from above and consider it in more detail. Based upon the question, what would be a reasonable hypothesis?

While studying eugenics, genetics plays a detrimental role in determining heredity. Genetics is the study and behavior of genes ("Genetics"). These genes are encoded pieces of information that comes from both parents, these genes are found on any of the 23 pairs chromosomes; these chromosomes that contain genes form the human genome. 22 chromosomes all contain the same genes although slight variations of alleles, alleles are alternate forms of genes, and the 23rd chromosome contains the information for the zygote's gender.

Much of how an individual turns out to be is not only dependant on the genes in which their parents have passed down to them, but also due to the family structure in which they were raised by.

GMOs (or “genetically modified organisms”) are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering, or GE. This relatively new science creates unstable combinations of plant, animal, bacteria and viral genes that do not occur in nature or through traditional crossbreeding methods.

that genes and environment must be considered in conjunction during the analysis of traits and

The field of genetics is at the center of modern scientific advancement, thus its demand for trained professionals to work in the research and clinical fields has increased exponentially over the years. I first gained interest in the field of genetics in grade 11 biology when it was first explained to me in an academic setting. My fascination only grew as my knowledge did. My ultimate goal in the field of genetics would be to work as a researcher of a clinical research organization such as Genome Canada or in a hospital such as The Hospital for Sick Children in their Centre for Applied Genomics.

The parade of genetically engineered marvels, during the past recent years, has been shocking: “Flavr-Savr” tomatoes that stay fresher longer; “giant salmon” that grow 37 times faster than the normal fish; “transgenic” pigs that are injected with human genes which causes them to produce milk with human protein that prevents blood clotting; and “supermice” injected with rat growth genes which makes them grow twice their normal size, are just a few.

TH Morgan concluded that chromosome play an important part in heredity and the passing on genetic traits

Genes build the phenotype of humans as well as the underlying genotype. Competition between cultural genes leads to varied success of genetic determinism. It can therefore be said that learnt traits such as those espoused within a specific culture, can produce what may seem to be the genetic genotype of an individual. Genes are not always advantageous in the

There has been a lot of scientific research done into genetics, genetic crosses and inheritance enabling us to understand why we have the certain characteristics and traits that we do, how we inherited them and how we can pass them on. It’s because of this research that we can understand and learn about our genetic makeup and why it effects the way we are.
