Basics of Genetics: Aaron, Andrew, Brian

Summary Genetics are the building blocks of life, without them we wouldn’t exist. Gregor Mendel was among the first to implore this area of study. Using pea plants to see traits of generations he built a better understanding of inheritance. Form Mendel’s work we have learned that in our body we have DNA and chromosomes, humans have 23 chromosomes. 22 of them are called autosomes and the last one is called the sex chromosomes, which determines your sex. You have two types of genes as well, genotypes which are the dominant traits (the ones that show), and phenotypes are the recessive ones (the ones that don’t show up). If your DNA or chromosomes are abnormal or mutates you run a high risk of some serious repercussions, like down-syndrome.

The breakdown of a chromosome.

This is the basic structure of a human cell and what it is made up of.
