In humans, red–green color blindness is an X-linked recessive trait. If a man with normal vision and a color-blind woman have a son, what is the chance that the son will be colorblind? What is the chance that a daughter will be color-blind?

Red-green colorblindness is inherited in an X-linked recessive pattern in humans.  A colorblind man and a woman with normal vision have four children, and one of them is a colorblind male.   Does the mother have to be a carrier in this case?  (Yes or No) What is the probability of the next child in this family being both colorblind and male?   No, 25% Yes, 25% No, 50% Yes, 50%

In humans, one type of red-green colorblindness (n) is sex-linked and recessive. A) A woman who is a carrier marries a man with normal vision. What is the chance of having color-blind daughters? Color-blind sons? B) A heterozygous woman and a color-blind man marry. What is the chance of having color-blind daughters? Color-blind sons?

In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f).  A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non‑freckled, normal visioned girl or a non-freckled, normal visioned boy?   What is the probability that the first four children born to the couple will be freckled and normal visioned girls?

One type of colorblindness is an X-linked recessive trait. If a colorblind man and a woman with normal vision but whose father was colorblind have a girl, what is the probability she will be colorblind? If they have a boy what is the probability he will be colorblind? 1/2 for the girl; 1/4 for the boy O 1/2 for the girl; 100% for the boy O 1/2 for the girl; 1/2 for the boy 1/4 for the girl; 1/2 for the boy O for the girl; 1/2 for the boy

Colorblindness is an X-linked recessive trait. If a color blind woman is married to a man with normal vision, what are the chances that the biological daughters from this marriage will be colorblind?

Amanda Sefton (Daytripper) has normal fingers and toes and normal color vision. Her mother is normal in all respects, but her father is color blind (X- linked recessive) and syndactylous (autosomal dominant). Kurt Wagner (Nightcrawler) is color blind and syndictylous. His mother has normal color vision and normal fingers and toes, but he didn't know his father. As their genetic counselor, answer the following questions based on Kurt and Amanda marrying and starting a family. What is the probability of having a child that has syndactyly?
