Question

can someone explain it better than my teacher did. I have no idea why the second equation is dividing by half

Given this mouse genetic map, how many recombinant gametes are expected from a set of 150 scored sperm? Round up to the nearest whole value recombinant scored sperm? Round 15....B 2 .c a) 30 b) 42 c) 48 d) 53 e) None of the above Offspring - parental +single and double recombinants 100% Parental-X (0.85)(0.8) (homolog 1) + = ½ (0.85)(0.8) (homolog 2) = 0.68 or 68% Recomb.10.68 0.32 0.32 X 150 = 48

Answer 1

The offspring can get gametes from both parents. One half of the genes will be from father and the rest half of the genes will be from mother. That is the reason behind dividing the equation by half.
