. In mice, the dominant allele Gs of the X-linked geneGreasy produces shiny fur, while the recessive wildtype Gs+ allele determines normal fur. The dominantallele Bhd of the X-linked Broadhead gene causesskeletal abnormalities including broad heads andsnouts, while the recessive wild-type Bhd+ alleleyields normal skeletons. Female mice heterozygousfor the two alleles of both genes were mated withwild-type males. Among 100 male progeny of thiscross, 49 had shiny fur, 48 had skeletal abnormalities,2 had shiny fur and skeletal abnormalities, and 1 waswild type.a. Diagram the cross described and calculate thedistance between the two genes.b. What would have been the results if you hadcounted 100 female progeny of the cross?
You have a female snail that coils to the right, but you do not knowits genotype. You may assume that right coiling (D) is dominant toleft coiling (d). You also have male snails of known genotype.How would you determine the genotype of this female snail? Inyour answer, describe your expected results depending on whetherthe female is DD, Dd, or dd.
In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor recessive gene. If 2 normal parents had a daughter with the symptoms ofthis disease, and a normal son, what is the probability that he might be acarrier of the recessive gene?Express answer in fraction form.
In cats, orange coat color is determined by the b allele, and blackcoat color is determined by the B allele. The heterozygous conditionresults in a coat pattern known as tortoiseshell. These genesare X-linked. What kinds of offspring would be expected from across of a black male and a tortoiseshell female? What are thechances of getting a tortoiseshell male?
What sex ratio would you expect among the offspring of a cross between a normal male mouse and afemale mouse heterozygous for a recessive X-linkedlethal gene? (b) What would be the expected sex ratioamong the offspring of a cross between a normal henand a rooster heterozygous for a recessive Z-linkedlethal allele?
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominantallele (coats are normally brownish). If a dwarf femalefrom a pure line is crossed with a pink male from a pureline, what will be the phenotypic ratios in the F1 and F2 ineach sex? (Invent and define your own gene symbols.)
man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give the genotypes and phenotype of offspring.
A man has attached earlobes, whereas his wife has freeearlobes. Their first child, a boy, has attached earlobes.a. If the phenotypic difference is assumed to be due totwo alleles of a single gene, is it possible that the geneis X linked?b. Is it possible to decide if attached earlobes aredominant or recessive?
Manx cats have no tail. This is caused by a dominantmutation M, which is embryo lethal when homozygous. An unlinked gene B controls the color of the fur onthe cat's tail. The dominant B allele produces black fur on tails, while the recessive allele b produceswhite fur on tails. A Manx cat that is B/B is crossed to a white-tailed cat. Half of the F1 progeny hadthe Manx phenotype and the other half had normal, black tails.The F1 cats with the Manx phenotype were crossed to each other, producing F2 cats. What is the ratioof the following phenotypes in the F2
Labrador retrievers may be black, brown, or golden in color (seethe chapter opening photograph on p. 53). Although each colormay breed true, many different outcomes occur if numerous littersare examined from a variety of matings, where the parentsare not necessarily true-breeding. The following results showsome of the possibilities. Propose a mode of inheritance that isconsistent with these data, and indicate the corresponding genotypesof the parents in each mating. Indicate as well the genotypesof dogs that breed true for each color.(a) black * brown ¡ all black(b) black * brown ¡ 1/2 black1/2 brown(c) black * brown ¡ 3/4 black1/4 golden(d) black * golden ¡ all black(e) black * golden ¡ 4/8 golden3/8 black1/8 brown(f) black * golden ¡ 2/4 golden1/4 black1/4 brown(g) brown * brown ¡ 3/4 brown1/4 golden(h) black * black ¡ 9/16 black4/16 golden3/16 brown
Two mothers give birth to sons at the same time at a busy urbanhospital. The son of mother 1 has hemophilia, a disease causedby an X-linked recessive allele. Neither parent has the disease.Mother 2 has a son without hemophilia, despite the fact thatthe father has hemophilia. Several years later, couple 1 suesthe hospital, claiming that these two newborns were swappedin the nursery following their birth. As a genetic counselor, youare called to testify. What information can you provide the juryconcerning the allegation?
