Australian researchers have found for the first time in animal experiments that a social competitive environment affects the "gender ratio" of sperm produced by males, and that the more intense the competition, the more sperm with the Y chromosome that makes offspring male. The findings could help with research into gender-related genetic diseases and animal breeding in humans.
male mammals produce two types of sperm. An X-containing chromosome, if it binds to an egg, the offspring will be female, and a Y-containing chromosome, if it binds to the egg, the offspring will be male.
In a paper published in the new issue of Evolutionary Letters, researchers at the University of Western Australia say they analyzed the growth of male laboratory mice in two different social environments: some male laboratory mice competed with each other, while male laboratory mice were accompanied by female laboratory mice.
University of Western Australia researcher Renee Philman, who led the study, said the results showed that male laboratory mice produced more sperm, better quality and more Y-chromosome sperm in a competitive environment with other male laboratory mice.
the first time that the "sex ratio" of sperm has been found to be related to the social environment in which the parents live, the researchers said.
Y chromosome sperm ratio means a larger proportion of males in offspring, and further experimental studies are needed, said Dr. Philman. (Source: Xinhua News Agency)
