2. Brown eyes are dominant over blue eyes in humans. Having a peaked hairline is dominant over having a smooth hairline in humans. Two such humans decide to have offspring – who will alse be human, because you know – genes. One of the parents has blue eyes and is heterozygous for a peaked hairline. The other parent is brown-eyed with a peaked hairline but is heterozygous for both traits. a) Complete a Punnett square showing all possible genotypes of their offspring. b) What is the probability of this couple producing a child with blue eyes?

Question

Transcribed Image Text:2. Brown eyes are dominant over blue eyes in humans. Having a peaked hairline is dominant over
having a smooth hairline in humans. Two such humans decide to have offspring – who will also
be human, because you know – genes.
One of the parents has blue eyes and is heterozygous for a peaked hairline. The other parent is
brown-eyed with a peaked hairline but is heterozygous for both traits.
a) Complete a Punnett square showing all possible genotypes of their offspring.
b) What is the probability of this couple producing a child with blue eyes?
c) What is the probability of producing a child who has both brown eyes and a smooth hairline?
