Question
Imagine that the Rf between genes A/a and B/b = 32%. Imagine also that the dominant wildtype A allele produces broad leaves, while the recessive variant a allele produces narrow leaves. The dominant wild-type B allele produces red berries, while the recessive variant b allele produces white berries. Imagine you perform the cross AaBb (A and B in cis) X aabb If you produce 100 offspring from this cross, how many offspring will have the genotypes and phenotypes below? broad leaves red berries broad leaves white berries narrow leaves red berries narrow leaves white berries
Explanation / Answer
The genes are 32 centimorgan apart giving rise to 100 progenies
The genotypic ratio if the cross is 1:1:1:1
Therefore gives rise to 25 progenies of the each recombinant genotype
