Answer #1

Answer:

Yellow-body = b

Wild-type = B

Heterozygote female (XBXb) x (XBY) wild-type male---Parents

Xb

Y

XB

XBXb (wild-type body female)

XBY (wild-type body male)

Xb

XbXb(yellow-body female)

XbY (yellow-body male)

Wild-type body female = 25%

Wild-type body male = 25%

Yellow-body female = 25%

Yellow-body male = 25%

    In Drosophila, genes a and b control body size and color, respectively. Large body (a+) is dominant over miniature (a), and gray body (b+) is dominant over ebony (b). The two genes are located at positions 32.0 and 40.0 on a particular autosome. Note that crossing-over does not occur in males. A miniature female that is homozygous for b+ was mated with an ebony male that is homozygous for a+. All the offspring were phenotypically wild-type (large body and gray).....
