Two plants in a cross were each heterozygous for two gene pairs (ab/ab) whose loci are linked and 20 map units (mu) apart. (recall that 1 mu is equal to 1% recombination between two genes.)
assuming that crossing over occurs during the formation of both male and female gametes and that the a and b alleles are dominant, determine the phenotypic ratio of their offspring.
what proportion of the offspring of two plants ( both (ab/ab)) will be a_b_ if the genes are 20 mu apart?
what proportion of the offspring of two plants ( both (ab/ab)) will be a_bb if the genes are 20 mu apart?
what proportion of the offspring of two plants ( both (ab/ab)) will be aab_ if the genes are 20 mu apart?
what proportion of the offspring of two plants ( both (ab/ab)) will be aabb if the genes are 20 mu apart?
