Based on the data shown in the graph, select the statements that describe what happens whenever one sex becomes rare or common. When one sex becomes rare, parents producing that sex have higher fitness due to a higher probability of mating success in their offspring. The rare sex becomes more common. When one sex becomes common, parents producing that sex have reduced fitness due to a lower probability of mating success in their offspring. The common sex becomes rarer. When one sex becomes rare, the other sex becomes common due to random fluctuations in the production of male and female offspring. The fitness of the parents is not affected. When one sex becomes either more rare or more common, parents produce an equal number of sons and daughters. The sex ratio returns to an equal number of males and females.
