In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one
of whom is blue-eyed. ("Actually, the situation is complicated by the fact that there is more
than one gene involved in eye color, but for this example, we'll consider only this one gene.)
1. A) If blue is recessive, what must the woman's genotype be?
1. B) If the man has brown eyes, but has a blue-eyed child what must his genotype
be?
or
1. C) If that's his genotype, what kind(s) of gametes (sperm) can he produce?

The upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the correspondingbones in whales have very different shapes and proportions. however, genetic data suggest that all three kindsof organisms diverged from a common ancestor at about the same time. which of the following is the mostlikely explanation for these data? a) humans and bats evolved by natural selection, and whales evolved by lamarckian mechanisms.b) forelimb evolution was adaptive in people and bats, but not in whales.c) natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy.d) genes mutate faster in whales than in humans or bats.e) whales are not properly classified as mammals.
