- Both Duchenne muscular dystrophy and color blindness are caused by recessive alleles. DMD, unlike color blindness, nearly always occurs in males. Explain why.In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if blue is recessive, what must the woman’s genotype be?In cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?
- If a pure breeding(homozygous) black(dominant), longhaired (recessive) cat is made of pure breeding Siamese, shorthaired cat, and one of their male offspring has made it to one of their female offspring, what is the chance of producing a Siamese colored shorthair kitten?Red-green color blindness is a sex-linked recessive trait in humans. Two people with normal color vision have a color-blind son. What are the genotypes of the parents? a. XXC and XY b. XX and XCY c. XCXC and XY d. XXC and XCYTwo cats are mated. One of the parent cats is long-haired (recessive allele). The litter which results contains two short-haired and three long-haired kittens. What does the second parent look like, and what is its genotype?
- Human blood types show both codominance and multiple alleles. The blood types are A, B, AB, and O. The alleles for A, B, and O are IA, IB, and i respectively. A and B are codominant, and O is recessive. Is it possible for a female with type AB blood and a male of type O to have a baby with AB blood?Skin color in humans is determined by polygenic inheritance, which means the more dominant alleles there are, the darker the skin color will be. A medium-toned skinned woman (AaBb) has a child with another medium-toned skinned man (AaBb). What is the probability of them having a very dark-toned skinned child? (Hint: the genotype is homozygous dominant)A woman with a colorblind father marries a colorblind man. What would be all possible genotypes and phenotypes of their offspring?
- Mr. and Mrs. Jones have six children. Three of them have attached earlobes (recessive) like their father, and the other three have free earlobes like their mother. What are the genotypes of Mr. and Mrs. Jones and of their numerous offspring?In humans, the ABO blood type is under the control of autosomalmultiple alleles. Red–green color blindness is a recessiveX-linked trait. If two parents who are both type A and have normalvision produce a son who is color-blind and type O, what isthe probability that their next child will be a female who has normalvision and is type O?Two guinea pigs are crossed. The father is hetereozygousblack and the mother is homozygous recessive white. What are the chances of getting a white baby guinea pig? Provide the phenotype ratio.
