Incomplete question, here is the full question: https://quizlet.com/153540854/biology-107-part1-flash-cards/
For the genetic structure of a population to change, we can either depend on natural selection or mutations but there has to be an imbalance.
The answers given in the options A and B are referring to changes in genotypes which surely affects the genetic structure of the population but the way these options are given is in equilibrium, meaning they create and imbalance but then counter that with something else.
In option C, some genotypes get a 5 percent increase while some get a 5 percent decrease in their reproductive success, which will most likely result in a change in the genetic structure of a population.
I hope this answer helps.
Answer;
A 5 percent increase in the reproductive success of some genotypes, but a 5 percent decrease in the reproductive success of other genotypes.
Explanation.
Genotypes with increaed reproductive success will have larger gene pool than other with 5% reduction.Thefore higher frequency of survival.Besides the high reproductive success ensure genetic variation which leads to changes in genome .
Full Question.
Which of the following would most likely lead to a change in the genetic structure of a population?
a. An increase of 1.1-fold in the reproductive success of all genotypes
b. A decrease of 20 percent in the reproductive success of all genotypes
c. A 5 percent increase in the reproductive success of some genotypes, but a 5 percent decrease in the reproductive success of other genotypes
d. Both a and b will likely change the genetic structure of the population more than c will.
e. None of the above is likely to change the genetic structure
