2. cross a woman carrier for hemophilia to a hemophiliac man. a) what fraction of the offspring will be carrier females? b) what fraction will be normal males? c) what fraction will be normal females--those who do not have the disease? d) what fraction will be hemophiliac females? e) what is the genotype of the carrier female? f) how many different genotypes are possible among the offspring?

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.

Number and variety of living organisms includes genetic, species, and ecological types

Amniocentesis is a process in which amniotic fluid is taken from the mother's womb to identify any genetic abnormalities in the fetus. how would the discovery of the human genome contribute to this process?
