ay be altered. Migration can increase or decrease gene frequencies in populations, resulting in...
greater genetic variation, which may enhance chances of survival.
less genetic variation, which will not influence chances of survival at all.

Which of the following is a dihybrid cross?a. RrMM Rrmmb. RRMM rrmmc. RrMm RrMmd. rrMM RRmme. RrMm rrmm
Minchanka [31]

Answer:

c. RrMm x  RrMm

Explanation:

A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.

Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).

This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.
