short eared mutant male rabbit was crossed with normal long eared doe rabbits and 29 long eared and 29 short eared rabbits were produced. The short eared rabbits were crossed among themselves and 31 short eared and 11 long eared rabbits were born. Determine which phenotype is dominant and explain the ratios with regards to the genotypes of the parents in each cross

Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?
A particular walnut rooster was crossed to a pea hen, and the progeny consisted of 12 walnut, 11 pea, 3 rose, and 4 single chickens. What are the likely genotypes of the parents?
In guinea pigs, the gene for black coat color is dominant to the gene for white coat color. What will be the genotypic ratio for the cross between two heterozygous parents?
A different walnut rooster was crossed to a rose hen, and all the progeny were walnut. What are the possible genotypes of the parents?
A rabbit with black fur (B) is crossed with a rabbit with white fur (b). All of the offspring have black fur. What is the genotype of the black rabbit parent?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited?
In terms of a chi-square analysis, what ratio would be tested for the offspring of a monohybrid cross involving a pure-breeding dominant condition mated with a pure-breeding recessive condition?
If two walnut combed chickens are crossed, and a ratio of 3:1 walnut comb:rose comb offspring results, what were the genotypes of the parents?
In mice, short hair is dominant over long hair. If a heterozygous shorthaired male is crossed with a heterozygous female, what are the genotypes of the parents?
When a white guinea pig is crossed to a yellow guinea pig, all the progeny are cream-colored. From a cross of two such F1’s, the F2 showed 32 white, 66 cream, and 30 yellow guinea pigs. How is this trait inherited? _______________ Identify the genotype of the white guinea pig. ________ Identify the genotype of the yellow guinea pig. ________ Identify the genotype of the cream-colored guinea pig. ________ Identify the genotypes and the corresponding phenotypes of the F2 progeny. Give the genotypic ratio. __________________ Give the phenotypic ratio. ___________________
In pea plants, flower color is determined by one gene with two alleles, with the allele coding for purple flowers (P) being dominant to the allele coding for white flowers (p). If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?
The Labrador Retriever’s coat colours are black, yellow, and chocolate.Yellow is produced by the presence of a recessive epistatic gene, which has the effect of masking the black and chocolate colour genes. Black (B) is dominant to chocolate (b).Therefore, the possible genotypes and corresponding phenotypes are: Phenotype Possible Genotypes Black G__B__ Brown G__bb Yellow gg__ Predict the percentage of offspring that would be black in colour for each of the following crosses.
