3.Punnett square for eye color in fruit flies for a cross between a white-eyed female and a red-eyed male. Red eye color is dominant. The eye color gene is carried on the X chromosome. The simulation will show what ratio of their off-spring would be white-eyed and red-eyed, and what ratio of each of these would be male and female. Draw the square and explain the cross.© BrainMass Inc. brainmass.com April 1, 2020, 10:49 am ad1c9bdddf
See the attached file.
Female, white eye: X-X-
Male, red eye: X+Y
(where - is recessive allele for white eye, and + stands for dominant red eye)
Female can only contribute X- because that's all she has. ...
The solution draws the square and explains the cross.
