Question

1. True or False: Beneficial mutations arise in response to the introduction of selective pressure to allow organisms to survive?

2. Which of the following explains why organisms with diploid genomes are better able to tolerate mutations?

A. Haploid organisms lack DNA repair pathways

B. Suppressor mutations can only occur in diploids

C. Most mutations produce recessive alleles

D. Diploid organisms have lower mutation rates

E. Forward mutation is more frequent than reverse mutations

3. A surfer dude is sunbathing and the UV rays induce a mutation in one of his skin cells. This mutation makes cells 100x more likely to become cancerous and cause skin cancer. The surfer is very concerned that his future children will also be more likely to develop skin cancer. What would his genetics-savvy surfer bro tell him?

A. That’s just the man keeping you down. Skin Cancer is fake news!

B. Chill out, dude! that mutation won’t be inherited.

C. Hakuna Matata, bro. It’ll revert. Happens like 99%

D. Your kids will totally inherit that mutation, but their DNA repair pathways will fix it, so they’re cool.

E. Your kids are totally gonna get cancer. Lame…

Answer 1

Ans1. TRUE

Ans2. C Most mutations produce recessive alleles.

Explaination:- the diploid are better in a sense when their occurs an mutations in the recessive allele its effect is hidden by its dominant allele whereas in case of haploid genome if one gene is mutated it definitely shows its phenotypic trait.

Ans3. B. Chill out bro that mutation wont be inherited.

Explaination:- the mutation caused in this case is not germinal and is somatic thus no chances for its inheritence.
