1. A homozygous blue-eyed mouse with short whiskers mates with a homozygous brown-eyed mouse with long whiskers. All of their offspring have brown eyes and short whiskers. Which alleles are dominant? 2. A homozygous five-clawed cat is crossed with a homozygous six- clawed cat and all of the kittens have six claws. Which allele is dominant? 3. In humans, the five-fingered condition is recessive to the six-fingered condition. Yet, most people have five fingers. Explain how this can happen.

2. Uniparental disomy is a rare phenomenon in whichonly one of the parents of a child with a recessivedisorder is a carrier for that trait; the other parent ishomozygous normal. By analyzing DNA polymorphisms, it is clear that the child received both mutantalleles from the carrier parent but did not receive anycopy of the gene from the other parent.a. Diagram at least two ways in which uniparentaldisomy could arise. (Hint: These mechanismsall require more than one error in cell division,explaining why uniparental disomy is so rare.)Is there any way to distinguish between thesemechanisms to explain any particular case ofuniparental disomy?

Co- Dominance1) In cattle, the alleles for red coat (R) and white coat (W) behave as the co-dominants. Both red and white hairs are produced in the heterozygote producing a coat pattern that is called "roan." a) Give the phenotypic and genotypic ratios to be expected among the offspring from a cross of two roan animals. b) What are the expected genotypic and phenotypic ratios from a cross of a roan animal and a white one?
6. In certain plant species such as tomatoes and petunias, a highly polymorphic incompatibility gene Swith more than 100 known alleles prevents self-fertilization and promotes outbreeding. In this form ofincompatibility, a plant cannot accept sperm carrying an allele identical to either of its own incompatibility alleles. If, for example, pollen carryingsperm with allele S1of the incompatibility genelands onto the stigma (a female organ) of a plantthat also carries the S1allele, the sperm cannot fertilize any eggs in that plant. (This phenomenonoccurs because the pollen grain on the stigma cannotgrow a pollen tube to allow the sperm to unite withthe egg.)For the following crosses, indicate whether anyprogeny would be produced, and if so, list all possiblegenotypes of these progeny. a. ♂ S1S2× ♀ S1S2b. ♂ S1S2× ♀ S2S3c. ♂ S1S2× ♀ S3S4d. Explain how this mechanism of incompatibilitywould prevent plant self-fertilization.

F1 hybrids between two species of cotton, Gossypium barbadenseand Gossypium hirsutum, are very vigorous plants. However, F1crosses produce many seeds that do not germinate and a high percentageof very weak F2 offspring. Suggest two reasons for theseobservations.
23. In horses, black color is influenced by the dominant allele B and chestnut coat color is influenced by the recessive allele b. Trotting gait is due to a dominant allele T, pacing gait to the recessive allele t. A black trotter who is homozygous for both traits is crossed to a chestnut pacer. a. What are the genotypes of the Pgeneration? b. What will be the genotype and phenotype of the F1 generation? c. Draw a punnett square showing the cross of two F1 generation horses. What is the phenotypic ratio of all the combinations?
Recalling the eye pigment pathway in Drosophila, identify the phenotypes of the flies with the following genotypes. (w=white, bw=brown, cn=cinnabar red, st=scarlet red, se=sepia brown)
D) Genetics Problem show the table and word In certain breeds of chickens, the allele "B" is responsible for black feathers whereas the contrasting allele "b" produces feathers that are white. Another r pair of alleles influences the shape of the feathers. "F" produces straight feathers whereas the contrasting gene for "f results in the frizzled condition. Give the genotypic and phenotypic ratios to be expected from the following cross: white, frizzled hen with a heterozygous black, homozygous straight rooster. Genotypic Ratio: Phenotypic Ratio:
8 Rosettes are the dominant coat type (R) in guinea pigs while smooth coat is recessive (r). Of 1630 guinea pigs observed on an expedition in South America, 1190 have rosettes and 440 present with a smooth coat. a. If this muddle of guinea pigs is in Hardy-Weinberg equilibrium for the hair coat locus, what is the frequency of the recessive allele?
Problem Solving: In Drosophila, the gene that controls red eye color (dominant) versus white eye color is on the X chromosomes. What are the expected phenotypic results if a heterozygous female is crossed with a white-eyed male? In cats, S = short hair; s = long hair; XC = black coat; Xc = yellow coat; XCXc = tortoiseshell (calico) coat. If a long-haired yellow male is crossed with a tortoiseshell female homozygous for short hair, what are the expected phenotypic results?
