In fruit flies, eye color is a sex linked trait. Red (R) is dominant to white(r) eyes. In a cross
between a white eyed female and a red eyed male, what is the percentage of male offsprings
having white eyes?

In 1910, Thomas Morgan discovered traits linked to sex chromosomes in the fruit fly. The Punnett square above shows the cross between red-eyed females and white-eyed males. Fruit flies usually have red eyes. If a female and male offspring from the cross shown above are allowed to mate, what would the offspring probably look like?
