Genetic disorders cause an individual to have physical abnormalities and are inherited in various ways through genes on different sets of chromosomes. Humans have 23 chromosomes with one chromosome differentiating males and females. This article will focus on two types of genetic disorders: those inherited from sex chromosomes and those that involve autosomes, which include the other 22 chromosomes.

Punnett squares are used to determine the genetic and physical characteristics of an individual. The monohybrid cross is dealing with one type of gene and this type of cross has an outcome of four gametes produced. The dihybrid cross is dealing with more than one type of gene and it has an outcome of sixteen gametes.

HuntingtonÂ’s disease is a rare autosomal dominant mutation genetic disorder. This disease is a neurodegenerative genetic disorder, which means that throughout time, there is a progressive loss of function of neurons in the nervous system. The onset of this disease appears around thirty five to forty five years of age, and the affected person is only expected to survive around ten to twenty years after onset. There is no cure for HuntingtonÂ’s disease, but treatments have been proven usefu...

Reason as to why Saccharomyces cerevisiae (yeast) is the ideal model organism in science as well as in the brewing and baking industries. Through high quality lenses, a Dutch naturalist discovers yeast as a nonliving globular structure , whereas a French chemist proves this theory incorrect by discovering yeast as a living microorganism in alcoholic fermentation.

The immune system is the mechanism in which molecules known as antibodies or immunoglobulins are produced and made to become genetically diverse. This process allows for antibodies to make different combinations in order to be specific to certain viruses and bacteria. The genetic diversity helps protect our body from any types of sicknesses and diseases.

A mutation found in a family located in a small village near Milan, Italy may be the key to eradicating heart disease. A one amino acid difference in the HDL gene allows this small family to have extreme longevity despite small amounts of “good cholesterol” and excessive amounts of “bad cholesterol”.

Describes the basic meaning of the statistical tests. Punnet and chi square tests are used in genetics for statistical purposes. These tests benefit many because the allow anyone to see how relevant the results are with what is expected and if it is not just random chance that the results may have been one way.

After reading this article you should understand what a three-point test cross is. Not only will you understand what it is but you will be able to set one up, solve it, and see where recombination occurs. Finally, you will be able to map, in a general order, where the locus are in respect to the each other and calculate the interference.

These facts are geared towards the average person, for easy yet informative reading. These facts are intended to surprise each person who reads them. By emphasizing how genetics is part of our everyday lives, it is intended to open individuals eyes that science is all around us and it is very important!

The origins of bacteriology and the model organism Escherichia coli. As well as the reason why E. coli is one of the most commonly used prokaryote model organisms in genetics. This article lists the basic functions of Escherichia coli and its various phenotypes that are studied in place of eukaryote phenotypes.

Cell cycle consists of G1, S, G2, and M phase. G1 phase consists of checkpoints that make sure cell has enough resources to move to S phase. In S phase chromosomes are duplicated. Then, G2 checkpoint makes sure DNA is duplicated accurately to proceed to M phase. M phase consists of mitosis (prophase, prometaphase, metaphase, anaphase, and telophase) and cytokinesis.

Drosophila Melanogaster or more commonly known as Fruit Flies, are more complex than you would think. They are Model Organisms used for introduction Genetics classes all across the World. With little costs to support, rapid reproduction rates, and a variety of physical traits that can be easily observed under a microscope, they are key for studying.

Genetics is the study of genes and this article will go over how we study genes and why it is important to us as a society. With advances in pharmacology and stem cell research, we can help eliminate diseases in our world and even help end world hunger. With genetics, we can help create a more perfect world.

Genetic Information is essential when determining and tracing diseases. Many of the most radical diseases today can be attributed to hereditary genes of an organism. Disease such as AlzheimerÂ’s and even cancer are believe to be hereditary. However, new disciplines such as Epigenetics can change the way we view and treat diseases from now on.
