Dominant Allele

An allele that produces it's phenotype in heterozygous and homozygous form.
An allele that produces its phenotype only in homozygous form

Recessive allele
Individuals of the same phenotype that, when crossed, always produce offspring with the same phenotype.

Pure line
Cross between homozygous parents with different genotypes

hybrid
Reciprocal cross

phenotypes of the male and female are reversed compared with a prior cross.
A cross between a homozygous recessive individual and someone with a dominant phenotype but an unknown genotype.

Testcross
Gene located on the X chromosome

X-linked
Gene located on the Y chromosome

Y-linked
Autosomal

Gene located on an non-sex chromosome or a trait determined by an autosomal gene.
Adults used in an initial experimental cross.

Parental generation
Mating of parents who carry two different genetic determinants for the same trait is called..

Monohybrid cross
When two members of each gene pair segregate into different gamete cells during the formation of eggs and sperm is

The principle of segregation.
Mating between two individuals that are heterozygous for two traits is considered to be

Dihybrid cross
When alleles of different genes are transmitted independently of one another is called.

Principle of independent assortment.
