Help me answer the following multiple choice questions

1. As far as blood type is concerned, the relationship between the IA allele and the i allele is

a) Codominance

b) Incomplete dominance

c) Epistasis

d) Incomplete expressivity

e) Complete dominance

2. An X-linked recessive lethal mutation exists in the general human population (assume that no new mutation arises, that the only source of this mutation is what already exists in the population, and that heterozygotes are completely normal). This lethal mutation leads to death well before reproductive maturation. Based on this information, who can pass on this lethal mutation to the next generation?

a) males only

b) females only

c) neither male nor female

d) both males and females

3. A mutation leads to a single amino acid replaced by another amino acid in the encoded protein. The mutated protein is relatively normal and can perform its function well when it is correctly folded into its 3D structure. However, the mutated protein is slightly less stable in its 3D structure. Compared to the wild-type protein, the mutated protein is more likely to unfold from its correct 3D structure into an incorrect one. This mutation is likely

a) pleiotropic

b) semi-dominant

c) temperature sensitive

d) recombinable

4. If a gene on an autosome is imprinted, which of the following would be true regarding the progeny of two heterozygous parents? Assume that there are only two alleles involved: G conveys a completely dominant phenotype and g conveys a completely recessive phenotype. In the answers below, the word phenotype refers to phenotype conveyed by the G/g gene only.

a) All the GG progeny have the same phenotype.

b) The male Gg progeny always has a phenotype that is different from the female Gg progeny.

c) All the Gg progeny have the same phenotype.

d) The gg progeny do not all have the same phenotype; it matters which g allele comes from which parent.

5. In one completely normal cell of one particular animal, there are 7 chromosomes. Which of the following stages is this cell most likely to be at?

a) G1

b) Immediately after Telophase is completed

c) Metaphase I

d) Anaphase II e) Metaphase II
