In fruit flies, the allele for white eyes is recessive to the allele for red eyes. in a generation of fruit flies, 45 males with white eyes, 46 females with white eyes, 44 males with red eyes, and 47 females with red eyes are produced. which of the following is the best conclusion you can make about the parents of this generation?

a.) one parent was heterozygous for eye color and the other was homozygous with red eyes.
b.) both parents were homozygous with red eyes.
c.) one parent had white eyes and the other was heterozygous for eye color.
d.) both parents were heterozygous for eye color.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
