Different forms of a gene

We receive 1 set of chromosome from each partens that contains the same genes in the same position

Chromosome theory of inheritance

DNA replication

A process where the DNA molecules split apart to make two identical copies

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
