Best ResponseYou've already chosen the best response.0You can find this without drawing the punnet square too. For the cross \(\sf BbX^AX\) (female) \(\times \sf BbXY\) (male) Probability of brown = 3/4 Probability of female = 1/2 Probability of Normal vision= 1 (color blindness is recessive xlinked, and father has no \(\sf X^A\) allele) Probability of brown + female + normal vision = \(\sf Large \frac{3}{4} \times \frac{1}{2} \times \frac{1}{1}=\frac{6}{16}\) So, 6 among 16 offsprings will be girl+Normal vision+Brown color

Best ResponseYou've already chosen the best response.0There was another possibility, if we take male as \(\sf BBXY\) and cross it with female \(\sf BbX^AX\) then probability of females with brown eyes and normal sight comes 1/2
