Chromosome theory of inheritance
DNA replication

genes
a section of DNA on a chromosome that controls a trait or characteristic
ex. eye color, hair color, and height
Allele
different forms of a gene
eye color (blue or brown), height (tall or short)
Dominant
Alleles that always show up in a organism when it is presented

will only show up if dominate alleles is not present
