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?

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?

Red-green color blindness is an X-linked recessive trait. Heterozygous females have normal color vision but are carriers of the allele for red-green color blindness. Based on the information presented in the pedigree, select all of the females from the list below that are known carriers of red-green color blindness.

Red-green color blindness is due to an X-linked recessive allele in humans. A widow�s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele. Consider the following family history: A man with a widow�s peak and normal color vision marries a color-blind woman with a straight hairline. The man�s father had a straight hairline, as did both of the woman�s parents. Use the family history to make predictions about...

Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons...

6. A brown-eyed man, whose mother was blue-eyed, marries a blue-eyed woman. The man is red-green colour blind and his wife has normal colour vision although her father was also colour blind. (Note: brown eyes is dominant over blue eyes and eye colour is inherited autosomally. Red-green colour blindness is a sex-linked recessive trait). a) What are the genotypes of the man and his wife with respect to these two traits? Ger b) Complete the...
