Question

16. In a particular plant, leaf color and leaf shape are controlled by two linked genes. Leaves of the wild-type plant are red. A recessive mutation in this gene causes white leaves. Wild-type leaves are pointed and a recessive mutation in this gene causes them to be smooth. The following cross was performed:

Heterozygous red, pointed x Homozygous white, smooth

RESULTS: 43 white, smooth
42 red, pointed
8 white, pointed
7 red, smooth
What is the recombination frequency between the gene for leaf color and the gene for leaf shape? ______

What is the recombination frequency between the gene for leaf color and the gene for leaf shape? 15%

=15/100=0.15=15%
