Question

Question 19 1 pts R. A. Fisher (1930) and Herman Muller (1932) proposed that sex accelerates adaptive evolution. Which of the following statements is NOT true for this Fisher- Muller model? In asexual populations, there are some alternative ways to combine one beneficial mutation in one individual with another beneficial mutation from another individual O O One advantage of sexual reproduction is that recombination allows natural selection to operate at a quicker rate than is possible in asexual species. Sexual reproduction makes it possible to have a combination of several beneficial mutations in the same individual by breaking down linkage disequilibrium In sexual populations, recombination can bring two beneficial mutations together even when one mutation does not arise in an individual that already has the other beneficial mutation.

Explanation / Answer

19_a) in asexual population, there are some alternative ways to combine one beneficial mutation in one individual with another beneficial mutation from another individual.

20 a) sexual selection

22 d) polyandry

Male potential reproductive success will often be lowest when he shared access to a single female (polyandry), and then male reproductive success will increase in the following order: sole access to a single female ( monogamy) , joint access to two females (polyhynandry) and access to numerous female(polygyny)
