True Breeding

The cross-pollination of two true breeding organisms.

Hybridize

True breeding parents are hybridized.

Parental Generation (P)

F2

Version of a gene

Allele

What are traits determined by?

Two Alleles

Determines organisms appearance

Dominant Allele

Has a noticeable influence on organisms appearance.

Recessive Allele

one, one

The observable trait of an organism

Phenotype

The genetic makeup of an organism

Genotype

Two different alleles for the same gene.

Heterozygous

Two of the same allele for a gene.

Homozygous

Two alleles for a given character separates during gamete formation, and go into different gametes.
