What is heterozygote advantage?

Q: What is heterozygote advantage?


A: Heterozygote advantage is a situation where an organism with two dissimilar alleles at a gene locus has greater fitness than an organism with two similar alleles.

Q: In which type of selection does heterozygote advantage occur?


A: Heterozygote advantage occurs in balancing selection.

Q: What is fitness?


A: Fitness refers to an organism's ability to survive and reproduce in a certain environment.

Q: What is a gene locus?


A: A gene locus is the specific location of a gene on a chromosome.

Q: What are homozygotes?


A: Homozygotes are organisms with two identical alleles at a gene locus.

Q: What is balancing selection?


A: Balancing selection is a type of natural selection that maintains genetic variation in a population and can lead to the preservation of multiple alleles at a gene locus.

Q: How does heterozygote advantage contribute to genetic variation in a population?


A: Heterozygote advantage can contribute to genetic variation in a population by maintaining multiple alleles for a gene locus, as both alleles are beneficial and neither is selected against.
