106US Gregor Mendel performed numerous dihybrid crosses between pea plants. Dihybrid
crosses involve the study of the inheritance patterns related to two different traits. In guinea pigs
the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur
(F) is dominant over the allele for long fur (f). What percentage of the offspring from a BbFf x bbff
cross would be expected to be heterozygous for both traits?
F 0%
G 25%
H50%
J 100%

Answer: 25% of the offsprings will be heterozygous for both traits

Explanation: A cross between BbFf and bbff will yield 16 offsprings with four different possible genotypes: BbFf, Bbff, bbFf, and bbff. Only BbFf is the genotype that is heterozygous for both traits, and there are four offsprings with BbFf genotype.

Therefore the percentage of the offsprings that are heterozygous for both traits is 4/16 x 100 = 25%

See the punnett square for the details of the dibybrid cross
