Black coat colour in cocker Spaniels is governed by a dominant allele B and red coat colour by its recessive allele b; solid pattern is governed by the dominant allele of an independently assorting locus S, and sported pattern by its recessive allele s. A solid black male is mated to a solid red female and produces a litter of six pups: two solid black, two solid red, one black and white, and one red and white. (a) What are the possible genotypes of all the phenotypes obtainable? (b) Determine genotype of the parents. Hint- an unknown portion of a genotype may be indicated by a dash (-).

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?
In cats, the locus for orange coat color is sex linked. Male cats that are black have the o+ allele, whereas those that are orange have the o allele. Females can be homozygous for the orange allele or homozygous for the black allele and will express each color, respectively. Heterozygous females are tortoise-shelled or calico, having orange and black patches. A calico cat, in addition to being heterozygous at the orange locus, also is either heterozygous or homozygous for the incompletely dominant, autosomal spotting allele (SS = large spots, Ss = small spots, ss = no spots). Manx tails are caused by a dominant trait that is lethal when homozygous. Long tails are the result of a homozygous recessive genotype. An orange male with small white spots and a manx tail is crossed to a calico female with small white spots and a manx tail. What is the probability of observing a solid black female with no spots and long tail? (Hint: All calico cats are female!)
The gene for flower color in snapdragons displays incomplete dominance. Snapdragons homozygous for the allele for red flower color have the genotype FRFR and have red flowers. Snapdragons homozygous for the allele for white flower color have the genotype FWFW and have white flowers. Heterozygous snapdragons, with the genotype FRFW, have pink flowers. A snapdragon that has pink flowers is crossed with a different snapdragon that has pink flowers. What percentage of the offspring is expected to have red, white, and pink flowers?
In cats, white patches are caused by the dominant allele P while p/p individuals are solid colored. Short hair is caused by the dominant allele S, while s/s cats have long hair. A longhaired cat with patches whose mother was solid-colored and shorthaired mates with a shorthaired, solid-colored cat whose mother was longhaired and solid-colored. What kinds of kittens can arise from this mating and in what proportions? Outline the cross and assign genotypes, phenotypes, and proportions in the space below. Plong hair, white patchesxshort hair, solid colored s/s ; P/pS/s ; p/p F1 progeny: 1/4 s/s ; P/plong hair, white patches 1/4 s/s ; p/plong hair, solid colored 1/4 S/s ; P/pshort hair, white patches 1/4 S/s ; p/pshort hair, solid colored
a vaiety of snapdragon has flowers that can be white, red , yellow, and pink. yellow alleles are recessive to both white and red alleles. red and white alleles demonstrate incomplete dominance producing pink flowers. show the cross between a yellow and a pink flower- include the genotypes and phenotypes. can any of the offspring be yellow? explain.
In some cats, the gene for tail length shows incomplete dominance. Cats homozygous for the long tail allele (T) have long tails and cats homozygous for the short tail allele (t) have no tails. Heterozygous cats have short tails. Draw a Punnett square for a mating between a short tail cat and a cat with no tail. According to your Punnett square, what is the percent chance that they would have a kitten with no tail? A)0% B)25% C)50% D)75% E)100%
Labrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes are involved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Y codes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur but all yy individuals are lighter coloured and yellow. The B allele codes for the ability to make hair with the darkest colouration: BB and Bb individuals have black fur; bb dogs have a lighter shade which is chocolate. In the blank Punnet Square below, calculate and state the ratio of phenotypes that occur with a cross between two individuals with the genotype YyBb.
In rabbits, black hair is dependent on a dominant allele B, and brown upon arecessive allele b. Short-hair is due to dominant allele S and long hair to arecessive allele s. If a true-breeding black short haired male is mated with abrown, long-haired female, what will their offspring look like? What will be the genotypes of the offspring?
The presence of second allele (E) affects the coat color of German Shepherd. In particular, the presence of homozygous recessive ee produces yellow German Shepherd. Supposed a male German Shepherd, homozygous dominant for both alleles, is crossed with a female German Shepherd, homozygous recessive for both alleles, what are the phenotypes of the parents?
A walnut comb rooster is mated to three hens. Hen A, which has a walnut comb, has offspring in the ratio of 3 walnut to 1 rose. Hen B, which has a pea comb, has offspring in the ratio of 3 walnut to 3 pea to 1 rose to 1 single. Hen C, which has a walnut comb, has only walnut comb offspring. What are the genotypes of the rooster and the three hens?
In seals, long whiskers (W) are dominant over short whiskers (w). What are the genotypic and phenotypic ratios for the offspring produced by mating a seal that is homozygous recessive with one that is heterozygous?
in guinea pigs, rough coat dominant (r) to smooth coat (r) and black coat (b) is dominant to white caot (b). a rough black guinea pig bred with a rough white one produces 29 rough black offspring, 31 rough white offspring, 11 smooth black and 9 smooth white. give genotypes of parents, the probability for the offspring, and the actual number of each kinda offspring you would expect.
