O True O FalseIn a cross between mice the genotypes AB/ab 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 (/).

Explain your reasoning and state any assumptions you made.Recombination frequency decreases as the distance between two genes increases. True FalseA 3-point test cross produces the following numbers of offspring: + + a 348 How many double recombinant offspring are g x + 363 there? + X + 88 O 1 g +a 96 g + + 61 O 711 + X a 40 О 285 g x a 1 + + +
