11. In a dihybrid cross, we consider two traits at the same time. Suppose in a species of fish, long tail (T) is dominant over short tail (t) and blue body color (B) is dominant over green body color (b) and the genes for these two traits lie on two different chromosomes. Suppose we want to predict the offspring that would result from crossing a father who is heterozygous to both traits and a mother who is homozygous recessive for both traits. Genotype of the father: Genotype of the mother: Phenotype of the father; Phenotype of the mother:

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
1. Two normal visioned parents have a color-blind son. Give the genotype of both parents and the son. 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. a. What percent of their offspring will be yellow? b. What percent of their offspring will be black? c. What percent of their offspring will be tortoise shell? d. Why is it impossible to have a tortoise shell male offspring?
1. In guinea pigs, black coat color (B) is dominant over white (b), and short hair length (H) is dominant over long (h). a) A guinea pig that is homozygous for black coat color and heterozygous for short hair is crossed with a black coat, long-haired guinea pig which had a white-coated mother. Indicate the genotypes of each parent, their gametes, and complete a Punnett square which shows the genotypes of all offspring. b) What is the probability of obtaining offspring with the following characteristics: i) black coat color and long hair ii) a female with white coat color and short hair
40. A scientist is studying insect wing length. An individual from a pure-breeding parental line (P1), for which the VP is 40 mm2, is mated with an individual from a pure-breeding parental line (P2), for which the VP is 80 mm2. This results in F1 progeny that has a VP of 54 mm2. A cross between two F1 progeny results in offspring with a VP of 92 mm. What is the genotypic variance? Group of answer choices a. 14 mm b. 34 mm c. 32 mm d. 38 mm

(a) Diagram this cross, showing the genotypes and phenotypes. (b) What will the offspring be like if two F2 white guinea pigs are mated?
1. In guinea pig, fur color is determined by one gene, and fur length by another independently segregating gene.
