The long hair of Persian cats is recessive to the short hair of Siamese cats, but the black coat color of Persians is dominant to the brown-and-tan coat color of Siamese. Make up appropriate symbols for the alleles of these two unlinked loci. If a pure black, long-haired Persian is mated to a pure brown-and-tan, short-haired Siamese, what will be the appearance of the F1 offspring? If two of these F1 cats are mated, what is the chance that along-haired, brown-and-tan cat will be produced in the F2 generation? (Use the shortcut probability method to obtain your answer; then check it with a Punnett square.)

The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?

The long hair of Persian cats is recessive to the short hair of Siamese cats, but the black coat colour of Persians is dominant to the black-and-tan coat of the Siamese. a) If a true-breeding black long-haired Persian is mated with a true-breeding black-and-tan short-haired Siamese, what are the predicted phenotypes of the cats in the F1 generation? b) If two of the F1 generation cats are then mated, what is the chance of obtaining a long-haired black-and-tan cat in the F2 generation? Your answer
In chickens, the Leghorn variety has white feathers due to an autosomal dominant allele. Silkies have white feathers due to a recessive allele in a second (different) gene. If a true-breeding whiteLeghorn is crossed to a true-breeding white Silkie, what is theexpected phenotype of the F1 generation? If members of the F1generation are mated to each other, what is the expected phenotypic ratio of the F2 generation? Assume the chickens in the parental generation are homozygous for the white allele at one gene andhomozygous for the brown allele at the other gene. In subsequentgenerations, nonwhite birds will be brown.
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?
In rabbits, the coat color black dominant (B) over brown (b). Short hair is dominant (S) over long (s). In a cross between a homozygous black short-haired male and a brown homozygous long-haired female, what would be the ratios for genotype and phenotype of the F1 generation?
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 snapdragons, red flower color (R) is incompletely dominant over white flower color (r), so that the heterozygote has pink flowers. A red snapdragon is crossed with a white snapdragon, and the F1 are intercrossed to produce F2. What is the genotype and phenotypes of the F1 and F2, along with their expected proportions? If the F1 are backcrossed to the white parent, what will be the expected genotype and phenotype of the offspring? If the F1 are backcrossed to the red parent and the resulting progeny are intercrossed, what is the expected proportions of genotypes and phenotypes in the progeny?
In the dihybrid cross AaBb ´ aabb, what proportion of individuals are expected to be homozygotic for both genes in the F1generation? Assume that in guinea pigs, dark brown fur (B) is dominant to black fur (b). If you mate a homozygous black guinea pig with a heterozygous brown guinea pig, what proportion of the progeny will be black? Assume that in guinea pigs, dark brown fur (B) is dominant to black fur (b). If you mate a black guinea pig with a homozygous brown guinea pig, what proportion of the progeny will be homozygous?
In dogs, wire-haired (H) is dominant to smooth-haired (h). In a cross of a homozygous wire-haired with a smooth-haired dog, what will be the phenotype of the F1 generation? What would be the genotype? What would be the ratio the wire-haired dogs in the F1 generation? What are the phenotypic and genotypic ratio?
What progeny would result from crossing a homozygous rose-combed hen with a homozygous pea-combed rooster? What phenotypes and ratios would be seen in the F2 progeny?
In dogs, black coat color (B) is dominant to yellow coat color (b), and straight fur (C) is dominant to curly fur (c). The coat color gene and the fur texture gene are on different chromosomes, so they assort independently, and are not sex-linked. In a cross between two BbCc parents, given that an offspring has black coat color and straight fur, what's the probability that it is heterozygous for both genes? Give 2 digits past the decimals.
