In fruit flies, the allele for eye color is carried on the X-chromosome. Normal red eye color (R) is dominant over white eye color (r). X^R is the allele for the normal red eyes and X^r is the allele for white eyes. Using the cross X^RX^r x X^R Y, what will be the eye color of their male children? 100% of their male children will be red eyes

25% of the male children will be red eyes, 75% will be white eyed

0% of the males will be white-eyed

50% of the males will be red eyes; 50% of the males will have white eyes
