In an individual that is heterozygous at three loci, the number of possible gamete types is?
n is the number of heterozygous loci, and types of gametes equal 2 n. With three heterozygous loci, a diploid organism might produce 2 3 = 8 gametes.
In terms of genetics, heterozygotes are people who have inherited various alleles (variations) of a certain genomic marker from each of their biological parents. An individual who possesses two copies of a genetic marker is said to be heterozygous. A person who has identical copies of two different markers, however, is said to be homozygous. In diploid animals, each pair of chromosomes has two alleles, one from the mother and one from the father, for each gene that determines a trait. A gene's alleles, which can have two or more different forms, can all be found at the same locus on a chromosome. Different alleles for a particular trait can be said to be heterozygous.

It occurs when individuals with traits that are favorable for survival and reproduction are more likely to pass on those traits to their offspring than individuals with traits that are less favorable.
Over time, this leads to a gradual change in the population, as the proportion of individuals with favorable traits increases. This process is driven by the environment, which imposes challenges and opportunities that select for certain traits. As a result, species evolve and adapt to their environments, leading to the diversity of life that we see today.
