- In cats, black fur color is caused by an X-linked allele; the other allele at this locus causes orange color. The heterozygote is tortoiseshell. What kinds of offspring would you expect from the cross of a black female and an orange male? For full credit, you must show all work.Albinism is an autosomal recessive condition where little or no melanin pigment is produced. Awoman (call her W) had an affected brother (B). This woman's daughter (M) is planning to have achild. The intended father (F) in this mating had a sister (S) who has albinism. W's father is red-green color blind (an X-linked recessive disorder). F's father is also red-green color blind. All other family members have normal vision. Re-draw the pedigree of thisfamily to include this extra information. Use defined symbols to indicate genotypes. g. Determine the probability that F will pass on red-green color blindness to his future children.h. Determine the probability that M is a carrier for red-green color blindness or for albinism i.Determine the probability that M is a carrier for red-green color blindness and for albinism i.Determine the overall probability that this couple's first child will be affected by bothconditions. k. Using the same genotypes as in part j for the couple, determine…In flies, long wings (W) are dominant to short wings (w). Two homozygous recessive flies are crossed.
- In flies, long wings (W) are dominant to short wings (w). Two homozygous recessive are crossed.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 F2Albino rabbits (lacking pigment) are homozygous forthe recessive c allele (C allows pigment formation).Rabbits homozygous for the recessive b allele makebrown pigment, while those with at least one copy ofB make black pigment. True-breeding brown rabbitswere crossed to albinos, which were also BB. F1 rabbits, which were all black, were crossed to the doublerecessive (bb cc). The progeny obtained were 34black, 66 brown, and 100 albino.a. What phenotypic proportions would have beenexpected if the b and c loci were unlinked?b. How far apart are the two loci?
- In bunny rabbits, red eye color (R) is dominant and white eye color (r) is recessive. The allele for eye color is carried on the X-chromosome. Which cross would most likely produce 50% white-eyed males and 50% red-eyed males? X'X x XRY XRXT xXY XRXRX X"Y O XRXRXXRYWhyte type canaries are yelllow. A dominant mutant allel of the color gene, designated W causes white feathers. Inheriting two dominant alleles is lethal to the embryo. If a yellow canary is crossed to a white canary, what is the probability that an offspring will be yellow? What is the probability that it will be white? [ autosomal special condition]Night blindness is an X-linked dominant disorder. An individual who has the genotype XNX" for night blindness is a genetic carrier homozygous dominant female with night blindness female with normal vision
- Hemophilia is a sex-linked recessive condition that results in deficient blood clotting. The disease causes excessive bleeding which occurs spontaneously or upon slight injury. In dogs (as in humans) hemophilia is caused by a defect in a gene on the X chromosome. What will be the results of mating between a normal, noncarrier female dog and a male dog with hemophilia? O All of the offspring will be normal, but all females will be carriers. All the female offspring will be normal and all male offspring will be carriers. O Half the male offspring will be normal and half will have hemophilia; all females will be carriers. O All female offspring will be normal and half the male offspring will have hemophilia.Scallly, rough skin, or ichthyosls, is a x-linked recessie trait found in humans (X*a); normal skin is dominant (X*A). Mike has ichthyosls ad he marries Carol whao has normal skin. The y have three boys and two girls. their own daugther has ichthyosls and the other daugther does not. The edest son hs ichthyosls and the othr sons have normal skin. What are the chances that they have a daugther with ichthyosls? What are the chances that they have a son with ichthyosls? Mike's gamete alleles? Carol's gamete alleles?Each box represents a potential offspring. Notice that genotypically speaking, they are all the same. Theyare all heterozygous (genotype) which means their phenotype is dark coloration. So, there is 100% chanceof producing a dark eyed, heterozygous offspring. What if that offspring mated with a light eyedindividual? Can you make a Punnett Square for that?Write the Genotypes and Phenotypes of the parents on the left of the square. Complete the square, thenwrite the potential offspring’s genotypes and phenotypes on the right of the square. Parents: Offspring:Genotypes: phenotypes: What are the genotypes of the resulting offspring? What are the phenotypes of the resulting offspring?
