2. In cats, the allele (B) produces black color but (b) produces a yellow color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell color. The alleles (B) and (b) are sex-linked as well. Cross a tortoise shell female with a yellow male.

In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds
2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
1. In rabbits, mono-colored fur (F) and straight ears (E) are dominant over spotted-fur and floppy ears. Your son owns a rabbit possessing white fur and floppy ears, and he mated it with another rabbit. The offspring of the rabbits turn out to be 8 in total. 4 are possessing white fur with straight ears, while the remaining 4 has spotted white and brown fur with straight ears. a. What are the traits (phenotype) present on the other rabbit mated to your son’s rabbit? Create a table to properly note the phenotypes and genotypes. Considering that your son continued breeding his rabbit to the original rabbit, what will be the probability that it will produce: b. male white fur with straight eared rabbit c. 2 male white fur with floppy eared rabbit d. 2 male white furred, straight eared rabbits and 4 female spotted white and brown, straight eared rabbits
4. Huntington diseases is a rare fatal, degenerative neurological disease in which individuals start to show symptoms in their 40s. It is caused by a dominant allele. Joe, a man in his 20s, just learned that his father has Huntington disease. a. What is the probability that Joe will also develop the disease?b. Joe and his new wife have been eager to start a family. What is the probability that their first child will eventually develop the disease?
2) In horses the color black is due to a dominant allele (B) and chestnut is due to the recessive allele (b). The trotting gait is due to a dominant allele (T) and the pacing gait to the recessive (t). a. What gametes would be produced by a homozygous black pacer? b. What gametes would be produced by a horse heterozygous for both traits?
1.) A long neck yellow giraffe (T t Y y) mates with a tall neck orange giraffe (T t y y). What is the percent chance their offspring would be have a short neck and orange? 2.) In humans, cataracts in the eyes and fragility of the bones are caused by dominant alleles that assort independently. A man with cataracts and normal bones marries a woman without cataracts but with fragile bones. The man’s father had normal eyes, and the woman’s father had normal bones a.) What are the genotypes of the man and the woman? b.) What is the probability that their first child will? (1) be free of both abnormalities (2) have cataracts but not have fragile bones (3) have fragile bones but not have cataracts (4) have both cataracts and fragile bones 3.) In corn plants, two pairs of genes control color in the ears of corn. The following genotypes result in various…
1. An albino man whose parents are both normal marries a woman one whose parents is normal and the other albino. She has an albino sister. The couple has a normal son. a. Is albinism a dominant or a recessive trait? Explain your answer. b.Give genotypes of all the persons involved. c. The couple plans to have more kids. What is the probability of their second child being normal?
8. In certain breeds of dogs, two different sets of alleles determine the color pattern. Black color is dominant and red color is recessive; solid color is dominant and white spotting is recessive. A homozygous black-and-white spotted male is crossed with a red-and-white spotted female. What is the probability of their producing a solid black puppy? Show your work.
1. A woman who is heterozygous for the brown eye and blue eye alleles marries a man with blue eyes. What are the genotypes and phenotypes of the children? a) What is the genotypic ratio of the above cross (Write number next to genotype)? ___________________________________________________________________ b) What is the phenotypic ratio of the above cross? (Write number next to phenotype)? ___________________________________________________________________
1. In guinea pigs, black hair (B) is dominant to brown hair (b) and short hair (H) is dominant to long hair (h). A heterozygous black, long-haired guinea pig is crossed with a brown, heterozygous short-haired guinea pig. What percentage of the offspring will be black with long hair?
1. In a particular bird species, the tips of the feathers are tinged with blue, white, or silver. The BB genotype calls for blue-tipped feathers. The WW genotype calls for white-tipped feathers. The BW genotype calls for an intermediate with silver-tipped feathers. A mating occurs between a blue-tipped bird and a white-tipped bird. What types of offspring would be expected? Give the genotypes and phenotypes of the possible offspring and the probability of each. 2. The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each. 3. In some cats, the gene for tail length shows incomplete dominance. When a cat with a…
