You perform a cross between two true-breeding strains of zucchini, One has green fruit and the other has yellow fruit. The F1 plants are all green, but when these are crossed, the F2 plants consist of 9 green: 7 yellow. A. Assuming that wild-type zucchini are green, how would you describe the phenomenon that occurred in the F1 of part (e) of the parents and progeny?.
In cats, the gene for calico (multicolored) cats is both sex-linked and codominant. Due to a phenomenon known as dosage compensation, females that receive a B and an R gene have black and orange splotches on white Males can only be black or orange, but never calico. a. What would a calico cat’s genotype be? b. Show the cross of a female calico cat with a black male. What percentage of the kittens will be black and male? c. What percentage of the kittens will be calico and male? d. What percentage of the kittens will be calico and female? e. Show the cross of a female black cat with a male orange cat. f. What percentage of the kittens will be calico and female? What color will all the male cats be?

You carry out a trihybrid cross (a cross in which the parental plants differ for three characters) between a tall pea plant with round, yellow seeds (TT RR YY) and a short pea plant with wrinkled, green seeds (tt rr yy). The parental plants are homozygous for all of the three characters. They are crossed to produce the F1 generation. Tall, round, and yellow are the dominant traits for each character. What will be the phenotypes of the F1 generation?
In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b. Short hair (H) is dominant to long hair (h). Show punnet squares In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like? If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype? If you carried out this test cross (from 2, using the F1 from 1), what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation of the cross in point 1?
In watermelons, bitter fruit (B) is dominant over sweet fruit (b), andyellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. Q. If an F1 plant is backcrossed with the sweet, unspotted parent, what phenotypes and proportions are expected in the offspring?
In cucumbers, orange fruit color (R) is dominant over cream fruit color (r). A cucumber plant homozygous for orange fruit is crossed with a plant homozygous for cream fruit. The F1 are intercrossed to produce the F2.a. Give the genotypes and phenotypes of the parents, the F1, and the F2.b. Give the genotypes and phenotypes of the offspring of a backcrossbetween the F1 and the orange-fruited parent.c. Give the genotypes and phenotypes of a backcross between the F1 and the cream-fruited parent
