1. Muscular dystrophy is an x linked recessive disorder. If two of the four offsprings have muscular dystrophy and the other two are normal, predict the genotype of the parents. The offsprins are all boys and the parents appear normal. 2. At age 50, the girl is bald and the boy is not bald. They are twins. What is the genotype of the girl? Predict the genotype of the parents of the twins.
8. In certain breeds of dogs, two different sets of alleles determine the color pattern. Black color is dominant and red color is recessive; solid color is dominant and white spotting is recessive. A homozygous black-and-white spotted male is crossed with a red-and-white spotted female. What is the probability of their producing a solid black puppy? Show your work.
1. Hemophilia is a disease inherited as a X-linked recessive trait while pattern baldness is controlled by an autosomal gene that is dominant in males and recessive in females. A hemophilic man who is also homozygous for baldness has children with a woman who is not hemophilic but a carrier and heterozygous normal-haired. Show the parental genotypes, the Genotypic ratio (GR) of the offspring and their phenotypic ratio. Separate the total number of the male offspring from female offspring. For example, if there are 8 total number of offspring, count how many are females and how many are males. So if there are 4 females, then the denominator for the genotypic ratio and phenotypic ratio for female offspring is 4. You can convert it to percentage if you want. Answer the following: a. Among the female offspring, what is the probability of having hemophilic but normal haired child? b. Among the male offspring, what is the chance of having a child with normal blood clotting but bald?
7. In pea plants, the dominant allele for flower color is yellow (Y), and the recessive allele is white (y).

Possible genotypes: Possible phenotypes:
4. The ruffed chicken has an under-chin wattle. A smooth wattle (S) is dominant over a wrinkled wattle (s). A red wattle (HR) is incompletely dominant with a white wattle (HW) so that an individual with HRHW will have a pink wattle. A chicken with a wrinkled red wattle is mated to a homozygous chicken with a smooth white wattle. What is the genotype and phenotype of the chicks?

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). Sex- linked 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 (X*Xª) with a man that does. Will the disorder in this particular cross be more common in daughters or sons?
