- Analysis of X-Linked Dominant and Recessive Traits A young boy is color-blind. His one brother and five sisters are not. The boy has three maternal uncles and four maternal aunts. None of his uncles children or grandchildren is color-blind. One of the maternal aunts married a color-blind man, and half of her children, both male and female, are color-blind. The other aunts married men who have normal color vision. All their daughters have normal vision, but half of their sons are color-blind. a. Which of the boys four grandparents transmitted the gene for color blindness? b. Are any of the boys aunts or uncles color-blind? c. Is either of the boys parents color-blind?Why are X-linked recessive disorders never passedfrom a father to a son?Most individuals who have X-linked diseases are males because O males have an extra Y chromosome. males have an extra X chromosome, making them XXY. O males have only one copy of the X chromosome. O the diseases are triggered by the male sex hormone, testosterone.
- A woman is color blind (an X-linked, recessive trait). What are the chances that her sons will be color blind? Show a punnet squareWilma and Wally have one male child who has been diagnosed withDuchenne muscular dystrophy, an X-linked condition that results insevere atrophy of skeletal muscle. Neither parent has this condition.What is the probability that their next child will have Duchenne musculardystrophy?Men are more likely to display an X-linked recessive disorder than are women. Why do you think this is true?
- A man with red-green color blindness marries a woman who is not color blind. They have 3 children, one of which is a color blind girl. What is the genotype of the mother? Color blindness is an X-linked trait.A recently married man and woman discover that eachhad an uncle with alkaptonuria (black urine disease), arare disease caused by an autosomal recessive allele of asingle gene. They are about to have their first baby. Whatis the probability that their child will have alkaptonuria?Number of FEMALE offspring that would have the condition of an X-linked trait, if an affected man and a carrier woman had children
- If a man has an X-linked recessive disease, can his sons inherit that disease from him? Why or why not?Color-blindness is an X-linked, recessive trait. If a normal-sighted woman, whose father was color-blind, marries a color-blind man, what is the probability that they will have a son who is color-blind? (use the letter “B”)Hemophilia (reduced blood clotting) is an X-linked recessive disease in humans. A woman with hemophilia mates with a man who exhibits normal blood clotting. What is the probability that their child will have hemophilia?
