Homework Answers
The color blindness is an X linked recessive disorder and the turners syndrome is caused due to nondisjunction of the chromosomes ie monosomy loss of an X chromosome. So a woman with turners syndrome will have the color blindness wherein the X chromosome should come from the mother and she wont get the sex chromosome from her father, which indicates that nondisjunction occurred in father. The nondisjunction might have occurred at either Meoisis 1 or Meoisis II.

SEX-LINKAGE Red-Green color-blindness is sex-linked X-linked recessive trait. A normal sighted woman whose father is color- blind marries a color-blind man. they have 20 children. Of those 20, 6 are normal sighted females, 5 are color-blind females, 4 are normal sighted males and 5 are color-blind males. 7. What are the genotypes of the parents and all the children? 8. Theoretically, what would be the genotypic and phenotypic ratios of the offspring?

Genetics Chapter 4: A color-blind woman with Turner syndrome has a father who is color-blind. Given that the gene for the color-blind condition is recessive and X-linked, provide a likely explanation (name and define the phenomenon involved) for the origin of the color-blind and cytogenetic conditions in the woman.
A woman with red-green color-blindness has a mother with normal vision.
A woman with red-green color-blindness has a mother with normal vision. Knowing that color-blindness is a sex-linked recessive gene, can you determine what her father's phenotype is? (yes or no) If so, what is it?The woman marries a man with normal vision. What is the probability they will have sons who are red-green color-blind? What is the probability they will have daughters who are red-green color-blind?

Suppose a woman with a color blind father and a mother with no history of color blindness in her family (i.e. she is homozygous dominant) marries a man with normal color vision. What are the likely genotypes and phenotypes of any children they have. (Note: your probability value should be given as a percentage - %) Briefly explain your answer

Suppose color blindness is a X linked trait in humans. It is also recessive. A phenotypically normal woman has a father with color blindness. This woman marries a man with normal vision. What is the chance of their children being color blind? What is the chance of their daughters being color blind?

22. [9 PTS] Turner syndrome results when an individual has a genotype of XO (a single X chromosome), and no other sex chromosomes. Color-blindness results from mutation of a single gene on the X chromosome. A couple, both of whom have normal color vision, have a color-blind child with Turner's syndrome. a. Did non-disjunction occur in the mother, or the father, or is it impossible to tell? Explain your answer. (3 pts) (continued next page. b. In the space provided...
