In ABO blood group inheritance, what is the relationship between the alleles IA and IB? a. They are pleiotropic to each other. (pleiotropic means one gene also influences two or more unrelated phenotypes) b. They are incompletely dominant to each other. c. They are codominant to each other. d. B alleles are dominant; A alleles are recessive. e. A alleles are dominant; B alleles are recessive.

In a trait that follows Mendelian rules of inheritance, what is the only way an organism can have the recessive phenotype? A. By having the homozygous recessive genotype B.

Fruit flies are very useful model organisms that have been used to study genetics. One mutant recessive trait in fruit flies is called "eyeless" because it causes flies to have no eyes. Cross an eyeless fly with a homozygous normal fly. a. Draw the Punnett square. b. What is the genotyoe ratio of the offspring? c. What is the phenotype ratio of the offspring? d. What genetic problem is this? (monohybrid, dihybrid or multiple allele)
Piebald spotting is a condition found in humans inwhich there are patches of skin that lack pigmentation. The condition results from the inability ofpigment-producing cells to migrate properly duringdevelopment. Two adults with piebald spotting haveone child who has this trait and a second child withnormal skin pigmentation.a. Is the piebald spotting trait dominant or recessive?What information led you to this answer?b. What are the genotypes of the parents?

If two heterozygous dogs were crossed to each other, whatwould be the probability of the following combinations of offspring?A. A litter of five pups, four with solid fur and one with spotted fur.B. A first litter of six pups, four with solid fur and two with spotted fur, and then a second litter of five pups, all with solid fur.C. A first litter of five pups, the firstborn with solid fur, and thenamong the next four, three with solid fur and one with spottedfur, and then a second litter of seven pups in which the firstborn is spotted, the second born is spotted, and the remainingfive are composed of four solid and one spotted animal.D. A litter of six pups, the firstborn with solid fur, the second bornspotted, and among the remaining four pups, two with spottedfur and two with solid fur
