Answer:
Proportion of the F2 male with red eyes and forked bristle will be 1/4
Explanation:
forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).
Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)
A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes
X+X+b+b+ x Xfbb
the F1 gives 1/2X+Xf 1/2b+b
1/2X+Y 1/2b+b
intercross of F1
Proportion of the F2 male with red eyes and forked bristle will be
forked bristle= Xfy = 1/2 and for red eyes 2/4= 1/2 = 1/2x1/2 =1/4
