Heritage Valley Farm uses Mendel's principles to guide their livestock breeding program. Their breeding manager applies dominance, segregation, and independent assortment to make informed decisions about which animals to mate for desired traits.

Listen
The cattle breeding program notices that heterozygous animals (Bb) for certain traits often have advantages over homozygous animals. This relates to Mendel's observations about hybrid vigor. What does this suggest about genetic diversity in breeding programs?
Question 1 options:

Homozygous animals are always superior because they show consistent traits

Only purebred animals should be used in breeding programs

Heterozygous animals often combine advantages from both alleles they carry

Genetic diversity has no impact on animal health or breeding success

Correct answer: Heterozygous animals often combine advantages from both alleles they carry.

Explanation: Hybrid vigor (heterosis) means heterozygotes can show improved fitness, health, or performance relative to homozygotes because they carry different alleles that can complement each other. This implies maintaining genetic diversity in breeding programs is beneficial. The other choices are incorrect because homozygosity is not always superior, exclusive use of purebreds can reduce diversity and increase inbreeding, and genetic diversity does affect health and breeding success.
