Red-green color blindness is an X-linked recessive trait in humans. Polydactyly (extra fingers and toes) is an autosomal dominant trait. Martha has normal fingers and toes and normal color vision. Her mother is normal in all respects, but her father is color blind and polydactylous. Bill is color blind and polydactylous. His mother has normal color vision and normal fingers and toes. When answering the given question, consider that the answers include the proportions of only some of the possible phenotypes other phenotypes are also expected to occur but are not included. If Bill and Martha marry, what proportions of children with specific phenotypes would they be expected to produce? 1/8 color-blind girls with normal fingers, 1/4 boys with normal vision and polydactyly 1/4 girls with normal vision and polydactyly, 1/8 boys with normal vision and polydactyly 1/8 color-blind girls with polydactyly, 1/8 boys with normal vision and normal fingers 1/4 color-blind girls with normal fingers, 1/4 boys with normal vision and polydactyly

Both red/green color blindness (R=normal, r=colorblind) and Duchenne-type muscular dystrophy (D=normal, d=muscular dystrophy) are X-linked recessive traits that map close to each other. A woman has a father who is red/green color blind. Her mother's family has a history of Duchenne's muscular dystrophy. This woman is apparently healthy with neither color blindness nor muscular dystrophy. She marries a healthy man and they have four sons and two daughters. Half the sons are healthy but color blind, the other half have normal color vision, but have Duchenne's muscular dystrophy. The daughters are both normal. What is the genotype of the woman? ** The notation is written as X/X (so the / separates the two X chromosomes in a female) Group of answer choices RD/rd rd/rd Rd/rD RD/RD

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 syndactylous. 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 syndactylous boy that is color blind? (Enter your answer as a decimal; Example = 0.8782)

Red-green color blindness is an X-linked recessive disorder. If Allison is heterozygous (a carrier), and her husband, Michael, is NOT colorblind. What is the chance that their male children will be colorblind? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?) 0% 25% or 1/4 50% or 2/4 75% or 4/4 100% or 4/4
Color blindness is an X-linked recessive disease. A female and a male with normal vision have 4 children. The phenotypes of the children are listed below: 2 Colorblind males, 1 normal vision female, one normal vision male. Given these results, the female must be a carrier for colorblindness. True False

If Bill and Martha marry, what proportions of children with specific phenotypes would they be expected to produce? The answers only include the proportions of some of the possible phenotypes; other phenotypes are also expected to occur but are not included. Assume full penetrance for both traits.

Tanya has a family history of colorblindness but can see colors, and her partner Tim is affected by colorblindness. Colorblindness is an X-linked recessive condition with the alleles: XB (unaffected and dominant) and Xb (affected and recessive). Tanya’s mother was affected, but her father was not. Her partner Tim is also affected. What is the probability that if Tanya and Tim had a daughter that she would be affected? How about a Son?
In humans, blue eyes are inherited as a recessive autosomal trait and color blindness is an X-linked recessive trait. A woman with blue eyes and normal color vision (her father was colorblind) marries a man who has normal color vision. The man has brown eyes, but his mother had blue eyes. What is the probability that this couple will have a son with brown eyes? What is the probability that this couple will have a color blind son with blue eyes?
Mary and Ron don't have albinism. However, is it possible for them to have a child with albinism? Explain. Stephanie has normal color vision. Her husband Chris also has normal color vision. They have a son that is color blind and a daughter that has normal color vision. What is the genotype of the mother, father, son and the daughter? Andy and Anne do not have polydactyl. Is it possible for them to have a child with polydactyl? Explain. When examining a pedigree chart, I notice that only males are affected. What does this tell me about the inheritance pattern? A man with blood type A marries a woman with blood type B. Their child has blood type O. What are the genotypes of the parents?
