Question

13. Diploidy can maintain genetic variation through

A. Hybrid vigor

B. Masking recessive alleles

C. Alternatively selecting for the rare phenotype

D. Assortative mating

E. Epistasis

14. When studying the evolutionary relationships between taxa that are more distantly related (e.g. sponges to mammals) it is best to study genes that

A. are neutral with regard to their effect on the phenotype

B. that accumulate mutations at slow rates possibly because selection removes most mutations

C. mutate rapidly and frequently

D. are pseudogenes

E. none of the above

15. A new plant species that forms because of polyploidy is likely to become established because

A. They can remain dormant for long periods of time.

B. They can reproduce asexually or parthenogenetically

C. They can reproduce sexually

D. They are allopatric to the parent species

E. None of the above
