A female fly that has miniature wings and sepia eyes is crossed with a male that has normal wings and is homozygous for red eyes

Eduardwww [97]

Answer and Explanation:

The gene that expresses the size of the wing is X-linked. The dominant allele expresses long wings, XM, while the recessive allele expresses miniature wings, Xm.

The gene that expresses the color of the eyes is autosomal. The dominant allele expresses red color, S, and the recessive allele expresses sepia color, s.

A female fly that has miniature wings and sepia eyes (XmXm ss) is crossed with a male that has normal wings and is homozygous for red eyes (XMY SS).

The F1 are intercrossed to produce the F2.

F1) 1/2 or 50% of the progeny are females and the other 1/2 or 50% are males

100% of the females (1/2 or 50% of the progeny) are long-winged and red-eyed

100% of the males (1/2 or 50% of the progeny) are miniature.winged and red-eyed.

F2) 8/16=4/8=1/2 or 50% of the progeny are females and the other 1/2 or 50% are males

Females (8/16):

3/8 of the females are long-winged and red-eyed, XMX- S-

1/8 of the females are long-winged and sepia-eyed, XMX- ss

3/8 of the females are miniature-winged and red-eyed, XmXm S-

1/8 of the females are miniature-winged and sepia-eyed, XmXm ss

Males (8/16):

3/8 of the males are long-winged and red-eyed, XMY S-

1/8 of the males are long-winged and sepia-eyed, XMY ss

3/8 of the males are miniature-winged and red-eyed, XmY S-

1/8 of the males are miniature-winged and sepia-eyed, XmY ss

Note: The symbol "-" means that in its place might be a recessive allele or a dominant allele. For example, S- means that it might be SS or Ss.
