Homozygous Dominant
pattern where the phenotypes of both homozygous parents are present in heterozygous offspring; both alleles are equally expressed
the branch of biology that studies heredity and variation in organisms
an organism that has two different alleles for a single trait, for example (Hh)
a genetic pattern in which neither of the two forms of a trait completely masks the other
a picture of all the chromosomes in a cell arranged in pairs
a chart or "family tree" that tracks which members of a family have a particular trait
what an organism looks like as a consequence of its genotype
Homozygous Recessive
occurs when groups of gene pairs act together to produce a specific trait
