Principles of Genetics and Breeding

13.1.10. Progeny testing

Progeny testing is a breeding programme that deciphers a parent's genotype by determining its offspring's phenotypes. Once the genotypes of the dominant parents are deciphered, selection is used to save the homozygotes and cull the heterozygotes, which will eliminate all copies of the recessive allele, fix the dominant allele, and produce a true-breeding population.
