n Drosophila melanogaster, forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal b
ristles (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. The F1 are intercrossed to produce the F2. What will the proportions of the F2 flies be (male with red eyes and forked bristles) from the cross?
Turtles eat the grass, grass is needed for fish breeding. If there are more turtles, they will eat more grass and there will obvious be less of it. If there is not enough grass, other populations of fish will leave because they can't breed.
