Please Help.QUESTION 13 Feather color in a certain species of bird is controlled by a pair of alleles that exhibit incomplete dominance. If birds that are homozygous for one allele are black and birds that are homozygous for the other allele are white, then heterozygous birds would be a. gray. b. white. c. black. QUESTION 20 Which of the following might explain how two separate genes control a single trait? a. One gene function better at higher temperatures. b. Both genes have the same alleles. c. There are two genes to control two separate steps in a pathway. d. Two genes cannot control a single trait.Question 7 Albinism is caused by an autosomal recessive allele that interferes with skin pigmentation in mammals. Two normally pigmented parents already have an albino boy. They plan to have 2 more children. a) What is the probability that their next two children will be normally pigmented? Show your work. b) What is the probability that their next two children will both have albinism? Show your work. c) What is the probability that, when they have 2 more children, they will end up with a family including a total of 2 albino children and one normal? Show your work. d) What is the probability that, when they have two more children, the next child (i.e. the second-born child) will be normal, followed by a child with albinism? Show your work. e) Explain why the answers to part (c) and part (d) are calculated differently.
