In cocker spaniels, black color (B) is dominant over red (b), and solid color (S) is dominant over spotted (s). If the genes are unlinked and the offspring of BBss and bbss individuals are then mated with each other, what fraction of their offspring will be black and spotted? (Hint: You will have to do two crosses!)

In Mendaliens, black fur (B) is dominant over gray fur (b), and red eyes (R) are dominant over purple eyes (r). The two characters show independent assortment. Determine the genotypes for the two parents that produced the following offspring: a) 100 black fur, red eyes: 100 black fur, purple eyes, 100 gray fur, red eyes: 100 gray fur, purple eyes b) 300 black fur, purple eyes: 100 gray fur, purple eyes

Black coat color of guinea pigs is a dominant trait, and white is the alternative recessive trait. If a pure black guinea pig is crossed to a white one what will be the phenotype and genotype of F1 offspring? If two F1 animals are mated what proportion of the F2 guinea pigs would be expected to be black?

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...

In guinea pigs, rough coat (R) is dominant over smooth coat (r) and black (B) is dominant over white (b). R and B are independent genes. Cross a homozygous rough black animal with a smooth white one. What are the genotypes and phenotypes of the offspring? Choose any two offspring and cross them, determining the genotypes and phenotypes of the next generation.

5. When two red-spotted tribbles are crossed, 9 of their offspring are red-spotted, 3 are solid red, and 4 are solid white. Two of the solid white tribbles are crossed with a solid red tribble and produce 1/2 solid red tribbles and 1/2 red-spotted tribbles. One of the solid white tribbles when crossed with a solid red tribble produces only solid red tribbles. A) List the alleles in this problem, then draw a punnette square that shows the original cross...

In tomatoes, red fruit (R) is dominant to yellow fruit (r). Round fruit (B) is dominant to pear-shaped fruit (b). Cross a heterozygous red, round tomato plant with another plant of the same genotype. Now, answer the following questions based on the above cross done by you: 1. What is the genotype of the first parent? 2. What is the genotype of the second parent? 3. What is the probability of getting heterozygous red and round fruit in the offspring?...

In guinea pigs, the allele for black coat color (B) is dominant over the allele for white coat color (b). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 31 guinea pigs, 2 are homozygous dominant, 11 are heterozygous, and 18 are homozygous recessive. What is the frequency of the recessive allele in the population? Show all work. A. 0.88 B. 0.12 C. 0.76 D. 0.64

3a. In a certain breed of dog long hair is dominant over short hair; the gene involved is autosomal. Another gene, B controls hair colour, which is X-linked, one allele B1 produces gray coloured hair; the other allele B2 produces red coloured hair; and the heterozygous combination B1B2 produces brindle coloured hair (a mix with patches of both gray and red coloured hairs). If a red male homozygous for long hair is mated with a brindle short-haired female, what kind...
