A linkage map shows the distance between gene 'a' and gene 'b' to be 40CM, how many of each genotype catergory would you expect among 100 offspring if you cross a cis double heterozygote with a double homozygote recessive? Each gene has two alleles, A & a and B & b, respectively. A. O AB/ab; 40Ab/ab; 40 aB/ab; 20 ab/ab B. 10 AB/ab; 40Ab/ab; 40 aB/ab; 10 ab/ab C. 30 AB/ab; 20 Ab/ab; 20 aB/ab; 30 ab/ab D. 40 AB/ab; 20 Ab/ab; 20 aB/ab; 20 ab/ab
