- The recombination frequency in a cross can never exceed 50%. Explain why is this limit?Recombination "hot spots " overestimate physical length. O True O FalseIn a cross between mice the genotypes AB/ab x ab/ab, what is the recombination frequency if the progeny numbers are 72 AB/ab, 68 ab/ab, 17 Ab/ab, and 21 aB/ab? The alleles are shown for each chromosome, separated by a slash (/)
