Step by step
Solved in 2 steps
- Would it be possible for a woman with an uncleft chinto have children with cleft chins? Use a Punnett squareand one or more hypothetical genotypes for the father todemonstrate your point.Assume that two parents with normal vision have a son who has red-green color blindness. Which parent is responsible for the son’s color blindness? a. the mother b. the father c. either parent d. None of these are correctExplain how the process of nondisjunction can result in an individual with Klinefelter syndrome. Create a diagram showing the disjunction occurring in the mother to help explain your reasoning.
- Can a male be a carrier of red-green color blindness?Which of the following syndromes is NOT possible for the individual produced in the diagram? a. Edwards syndrome b. Turner syndrome c. Klinefelter syndrome d. Down syndromeTwo normal visioned parents have a color-blind son. What are the genotypes of the parents?
- Suppose a woman has four sons, and two are colorblind but have normal blood clotting and two have hemophilia but normal color vision. What is the probable genotype of the woman? b. Suppose this woman (later on) had a son with normal vision and normal blood clotting. How can this be explained?How is this trait inherited? A. The trait is epistatic. B. The trait is X-linked. C. The trait is dominant. D. The trait is recessive.What would be the expected phenotypes and genotypes of the children when a color blind man marries a normal woman?
