b. an allele that is found on many genes
c. an allele that mutates with each generation
d. an allele present in all members of a population?
All humans are homozygous for alleles known as fixed alleles. Of course, many human characteristics are malleable. Height, eye color, and hair color are all variable. Thus, option D is correct.
An allele in which there are no other alleles for this location in the population, since everyone in the studied population is homozygous for it.
Genetic variety may be hampered by genetic drift, which may cause gene variations to completely disappear. Additionally, it can make previously uncommon alleles common and even fixed.
An allele is said to be fixed if it is the only variant of that gene in the whole population.
All individuals in the population have homozygosity for a fixed allele. Typically, the term “allele” refers to one alternative gene among many that could exist for a specific DNA region.
Therefore, an allele present in all members of a population.
