In human beings, a recessive X-linked mutation, g, causes green-defective color vision; the wild-type allele, G, causes normal color vision. A man and a woman (generation I), both with normal vision, have three children (generation II): a color-defective son, a daughter with normal vision, and a daughter with normal vision. In generation III , give the most likely genotypes for III-1. Assume anyone who married into the family does NOT have a history of this disorder.

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.
