Question

question 11 1 pts which involves breeding an organism that has the unknown genotype with one that is homozygous recessive for the desired trait? selective breeding test cross inbreeding

Explanation:

• Selective breeding is the process of choosing organisms with desirable traits to reproduce, but it doesn't specifically involve breeding with a homozygous recessive organism to determine genotype.
• Test cross: By definition, a test cross is when an organism with an unknown genotype (usually dominant - phenotype) is crossed with a homozygous recessive organism. The offspring phenotypes can then be used to determine the unknown genotype. For example, if \(A-\) (unknown genotype) is crossed with \(aa\) (homozygous recessive), if all offspring are \(Aa\) (dominant phenotype), the unknown genotype is \(AA\); if half are \(Aa\) (dominant) and half are \(aa\) (recessive), the unknown genotype is \(Aa\).
• Inbreeding is the mating of closely - related individuals, which is more about maintaining pure lines or increasing homozygosity in a population, not about determining an unknown genotype.

Answer:

Test cross
