True-Breeding

The offspring produced from self-fertilization remained uniform from one generation to the next.

Segregating

Some offspring exhibited one form of a trait and other offspring exhibited other forms of the trait.

Self-Fertilization

Gametes produced by the male and female parts of the same flower can fuse to form one viable offspring.

Reciprocal Crosses

using pollen from a white-flowered plant to fertilize a purple-flowered plant, then using pollen from a purple-flowered plant to fertilize a white-flower.

Alleles

Alternative forms of a gene.

Homozygous

two haploid gametes containing the same allele fuse during fertilization

heterozygous

two different haploid gametes contain different alleles.
