Organisms benefit from having homologous pairs of chromosomes because
A) if a mutation occurs, only the functional copy will be passed on to offspring.
B) a deleterious allele can be masked by the presence of a functional copy.
C) possessing two copies of chromosomes enables cells to more easily divide.
D) genetic variation is introduced into gametes through independent assortment.
Homologous Chromosomes
Pairs of chromosomes that have the same structure and gene sequence, one inherited from each parent.
Genetic Variation
The diversity of genetic characteristics within a species or population, which is a result of mutations, genetic recombination, and other processes.
Deleterious Allele
A version of a gene that, on average, decreases the fitness of the organism carrying it.
