All life is created by the building blocks of DNA. DNA is created by four nucleotides Adenine, Guanine, Thymine, Cytosine. Variants of the order of these nucleotides gives rise to all the diversity of life on our planet. Heridetary information are passed through genes in our chromosomes. Humans inherit half of their chromosomes from their mother and the other half from their father. Even the sex of the child depeneds on what chromosomes the child inherits.

High altitude residents have evolved over time through natural selection. Their phenotypes show larger chest sizes, an increase in lung capacity, and shorter extremities. These characteristics are advantageous to their overall survival and ability to reproduce. The ability for high altitude residents to adapt leading to evolution begins with the fact that on order to be able to express environmentally induced phenotypes, an individual must first contain an advantageous genotype.

This article discusses the usage of a pedigree chart and mainly what those pedigree symbols mean to a geneticist. In addition, the article explains why pedigree charts can help geneticists understand how a disease can be passed on to future generations and why Punnett sqauares can explain why a pedigree chart appears like it is.

This article contains general facts about genetically modified foods (GE foods), also known as genetically modified organisms (GMOs). This includes the process of how plants and animals are genetically modified, its dominance in the U.S. market and the benefits of GE foods. Additionally, environmental, health, and animal abuse concerns will also be discussed.

This article is related to genetics, the study of genes. More specifically, it deals with Point Mutations. This includes the different types of point mutations, from nonsense and missense mutations, and what they do to the genes. This article reveals why we are lucky to be who we are, and just makes it known of one of the wonders of the human body.

This article is about the use of homozygous recessive individuals for test crosses. Test crosses are used to see the recombination that occured in linked traits. Linked traits are alleles that are located on the same chromosome, sometimes very close together. These linked traits can interefere with one another, since they are so closely spaces. This article explains the use of test crosses, homozygous recessive individuals, and linked traits in general.

This is just the pure basics to a polymerase chain reaction. It focuses mainly on making the mix for the PCR and why the thermo cycler cycles through the different temperatures. This is a good reference for undergraduate college students learning what a PCR is and how to do one.
