Tom is CTOSS/ 3. Skin color in humans is determined by a polygenic
inheritance system, possibly involving involving as many
as 9 genes. For simplicity let's consider the influence of
3
genes: A. B, and C. where the dominant allele darkens
skin color. Suppose a women who is AABbCc mates
with a man who is AaBbcc.
A. List all of the possible genotypes of the gametes that
could be produced by each the parents?
B. Draw a Punnett square that shows the genotypes
possible, and number each genotype from lightest (1) to
darkest skin coloration.
C. In this cross, how many dominant alleles will children
with the darkest olin

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.
