14、ately equal numbers of males and females. Why should this be so? Two main kinds of answers have been offered. One is couched in terms of advantage to population. It is argued that the sex ratio will evolve so as to maximize the number of meetings between individuals of the opposite sex. This is esse
15、ntially a “group selection“ argument. The other, and in my view correct, type of answer was first put forward by Fisher in 1930. This “genetic“ argument starts from the assumption that genes can influence the relative numbers of male and female offspring produced by an individual carrying the genes.
16、 That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted. Suppose that the population consisted mostly of females: then an individual who produced sons only would have more grand children. In contrast, if the po
17、pulation consisted mostly of males, it would pay to have daughters. If, however, the population consisted of equal numbers of males and females, sons and daughters would be equally valuable. Thus a one-to- one sex ratio is the only stable ratio; it is an “evolutionarily stable strategy“. Although Fi
18、sher wrote before the mathematical theory of games had been developed, his theory incorporates the essential feature of a gamethat the best strategy to adopt depends on what others are doing. Since Fishers time, it has been realized that genes can sometimes influence the chromosome or gamete in whic
19、h they find themselves so that the gamete will be more likely to participate in fertilization. If such a gene occurs on a sex-determining ( X or Y) chromosome, then highly aberrant sex ratios can occur. But more immediately relevant to game theory are the sex ratios in certain parasitic wasp species
20、 that have a large excess of females. In these species, fertilized eggs develop into females and unfertilized eggs into males. A female stores sperm and can determine the sex of each egg she lays by fertilizing it or leaving it unfertilized. By Fishers argument, it should still pay a female to produ
21、ce equal numbers of sons and daughters. Hamilton, noting that the eggs develop within their hostthe larva of another insectand that the newly emerged adult wasps mate immediately and disperse, offered a remarkably cogent analysis. Since only one female usually lays eggs in a given larva, it would pa
22、y her to produce one male only, because this one male could fertilize all his sisters on emergence. Like Fisher, Hamilton looked for an evolutionarily stable strategy, but he went a step further in recognizing that he was looking for a strategy. 18 The author suggests that the work of Fisher and Ham
23、ilton was similar in that both scientists_. ( A) conducted their research at approximately the same time ( B) sought to manipulate the sex ratios of some of the animals they studied ( C) sought an explanation of why certain sex ratios exist and remain stable ( D) studied game theory, thereby providi
24、ng important groundwork for the later development of strategy theory 19 According to the passage, successful game strategy depends on_. ( A) the ability to adjust ones behavior in light of the behavior of others ( B) ones awareness that there is safety in numbers ( C) the degree of stability one can
