Amoeba sisters video recap alleles and genes key

Color blindness is a sex-linked recessive disorder on the X chromosome. If the allele “b” is used to denote color blindness, circle the genotype(s) that correctly represent(s) a female that is color blind. BB Bb bb XBXB XBYB XBXb XbY XbXb XbYb XB Y 7. Color blindness is a sex-linked recessive disorder on the X chromosome. If the allele “b” is used to denote color blindness, circle the genotype(s) that correctly represent(s) a male that is color blind. BB Bb bb XBXB XBYB XBXb XbY XbXb XbYb XB Y Sex-Linked Punnett Square Practice! 8. Bob is color blind, but he knows that neither of his parents were color blind. He is wondering if he received the gene for color blindness from his mother, his father, or both of his parents. What would you tell Bob? Show a Punnett square to prove your answer! 9. Consider the below Punnett square cross. Explain how you could use it to determine which parent determines the biological sex of a baby---is it the mother, father, or both? Why? 10. In the video example, the sex-linked disorder was a recessive trait. However, sex-linked disorders can be dominant! (Conduct a search to see some of the sex-linked dominant disorders that exist). Sexlinked dominant disorders will show even if there is only one dominant allele present. Using the allele D to stand for a dominant sex-linked trait, show a cross with a woman who does not have a dominant sex-linked disorder (XdXd) with a man that does. Will the disorder in this particular cross be more common in daughters or sons?
