What is the term for a mating specifically designed to reveal a parent's genotype at specific loci?

• A. Controlled Breeding
• B. Test Mating
• C. Genetic Testing
• D. Cross Breeding

Answer: (B)

The term that best describes a mating specifically designed to reveal a parent's genotype at specific loci is "Test Mating." This method involves mating individuals where the genotype of one or both parents is uncertain, with the aim of determining the genetic contributions from each parent based on the phenotypes of their offspring. This approach is particularly useful in breeding programs, allowing breeders to infer the genotypes of the parents by observing the traits expressed in their progeny and employing this information for future breeding decisions. Controlled breeding refers to the practice of carefully managing the mating process to achieve certain outcomes, but it does not specifically focus on revealing genotypes. Genetic testing typically involves analysis outside of breeding to identify specific alleles or genetic traits using molecular methods, rather than through traditional mating techniques. Cross breeding refers to the mating of individuals from different genetic backgrounds or breeds, aimed more at enhancing genetic diversity than specifically determining parent genotypes. Thus, Test Mating stands out as the precise answer to the query about revealing genotypes through mating practices.
