Fitness trade-off refers to selection favoring which genotype?

Question

Quizplus · Accepted Answer

Fitness trade-off refers to the phenomenon where selection favors a genotype that maintains a balance between two opposing traits. In this case, heterozygous individuals are favored because they have a balanced expression of both dominant and recessive alleles, allowing for greater flexibility and adaptability in changing environments. Homozygous dominant individuals may have an advantage in stable environments, but may be at a disadvantage if there is a sudden change in the environment. Homozygous recessive individuals may have an advantage in unstable environments, but may be at a disadvantage if the environment becomes stable again. Therefore, heterozygous individuals are the best choice as they have a balance of both traits and are better equipped to handle changing environments.
