A dog breeder understood that her spaniels could be solid coloured, spotted or white owing to their genotype at the spotted locus with alleles S, SP and SW responsible for the three phenotypes respectively. She also understood there to be a dominance hierarchy with solid coloured being dominant to the other two phenotypes and white being recessive to the other two phenotypes. She mated Grouse, a solid coloured black dog, with a white bitch producing a litter containing a black spotted pup. What was Grouse's genotype, and the genotype of the spotted pup, at the spotted locus? (Select all the correct statements). 1. Grouse S/S 2-Grouse S/S 3. Grouse S/SW 4. pup SP/SW 5.pup sº/s 6. pup S/Sº 7. There are more than one possible genotypes for Grouse 8. There are more than one possible genotypes for the pup

A mouse from a true-breeding population with normal gait was crossed to a mouse displaying an oddgait called dancing. The F1 animals all showednormal gait.a. If dancing is caused by homozygosity for the recessive allele of a single gene, what proportion ofthe F2 mice should be dancers?b. If mice must be homozygous for recessive allelesof each of two different genes to have the dancing phenotype, what proportion of the F2 shouldbe dancers if the two genes are unlinked?(Assume that all the mice in the populationwith normal gait were homozygous fordominant alleles.)c. When the F2 mice were obtained, 42 normal and8 dancers were seen. Use the chi-square test todetermine if these results better fit the one-genemodel from part (a) or the two-gene model frompart (b).
Professor John decided to breed bunnies during stay-at-home because why not. She performed the following cross:Parents:brown fur, gray nose x white fur, gray noseOffspring:3/8 white fur, gray nose1/8 white fur, white nose3/8 brown fur, gray nose 1/8 brown fur, white noseBased on the phenotypes of the offspring, what are the genotypes of the parents? Make sure you define your genotypes (ie B is brown fur, b is white fur)
Alleles that show incomplete dominance will represent: Choose oneAnswer: A . heterozygotes that have a phenotype intermediate between the dominant and recessive alleles. B. homozygotes that have a genotype like the recessive allele C. homozygotes that have a phenotype intermediate between the dominant and recessive alleles. D. heterozygotes that have a genotype like the dominant allele
With regard to heterosis, is each of the following statements consistent with the dominance hypothesis, the overdominance hypothesis, or both? A. Strains that have been highly inbred have become monomorphicfor one or more recessive alleles that are somewhat detrimentalto the organism. B. Hybrid vigor occurs because highly inbred strains are monomorphicfor many genes, whereas hybrids are more likely to beheterozygous for those same genes.C. If a gene exists in two alleles, hybrids are more vigorousbecause heterozygosity for the gene is more beneficial thanhomozygosity of either allele.
Roan color in cattle is the result of incomplete dominance between red and white color alleles (R/r) of a single gene that controls coat color. How would one produce a herd of pure-breeding roan-colored cattle? Choose an answer below: Cross roan with roan animals Cross red with white animals Cross roan with white animals Cross roan with red animals It cannot be done.
In pea plants, yellow seed color is the dominant trait, and green-seed color is the recessive. Use a punnett square to show the results pf a cross between a heterozygous yellow-seed plant and a green-seed plant.
In Ayrshire cattle, the spotting of the coat can be either red andwhite or mahogany and white. The mahogany-and-white phenotypeis caused by the allele SM (where the letter S indicates spotting, andthe superscript M stands for mahogany). The red-and-white phenotypeis controlled by the allele SR (where the superscript R standsfor red). The table below shows the relationships between genotypeand phenotype for males and females: Explain the pattern of inheritance.
In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?
The American Curl is a breed of cat that has curly ears. The allele for the curly ears is dominant (E). Suppose a cat with the heterozygous genotype is bred to a female cat with the homozygous recessive genotype. Fill out a Punnett Square and answer the following questions. What is the phenotypic ratio of this punnett square? If this cross produces six kittens, how many of them will have curly ears? ________
A cross between two pea plants, both of which grewfrom yellow round seeds, gave the following numbersof seeds: 156 yellow round and 54 yellow wrinkled.What are the genotypes of the parent plants? (Yellowand round are dominant traits.)
When you decide to breed your Labrador retriever Molly and sell the puppies, you discover that two of Mollys four siblings have developed a hip disorder that is traceable to the action of a single recessive allele. Molly herself shows no sign of the disorder. If you breed Molly to a male Labrador that does not carry the recessive allele, can you assure a purchaser that the puppies will also be free of the condition? Explain your answer.
The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?
