Question

When a red-flowering (RR) snapdragon is crossed with a white-flowering snap dragon (rr) all the offspring in the first generation (Rr) produce flowers of an intermediate color (pink-flowering). This type of inheritance is an example of:

Select one:

a. Dominance

b. Codominance

c. Incomplete Dominance

d. Homeostasis

Which of the following could generate an inherited cancer allele?

Select one:

a. Error by DNA polymerase during meiosis

b. Error by DNA proofreading enzymes during mitosis

c. Mutation to the DNA in pancreatic cells

d. Somatic mutation

Explanation / Answer

1st question answer:

c. Incomplete dominance (One of the alleles synthesizes some functioning protein while the other allele is nonfunctional. which leads to development of new characters)

2nd question answer:

b. Error by DNA proofreading enzymes during mitosis (because activity of polymerase and exonuclease causes the error in DNA replication, but if there is any error that should be corrected by proofreading)
