Prof. Ronny Rahman Noor: Sex of Living Things is Determined by Many Factors

Prof. Ronny Rahman Noor, Professor of the Faculty of Animal Science, IPB University, gave an explanation about the sex of living things. He explained that there are many factors that determine the sex of living things. He also claimed that Aristotle's theory was not entirely wrong.

"The effect of temperature described by Aristotle in determining the correct sex is not wrong. This is, after science on how to determine sex developed, it turns out that there are indeed types of living things such as reptiles that are born with different sex types due to the effects of their nests' temperature," this geneticist from IPB University.

He further explained that the sexes of various living things are indeed various. However, one of the most common is the presence and role of sex chromosomes.

“In general, every living thing, both male and female, has the same number of chromosomes. The difference in the chromosomes possessed by male and female individuals is in a pair of sex chromosomes," he added.

He gave an example, the number of chromosomes in humans, both male and female, is 46 chromosomes that are paired with each other. Thus, there are 23 pairs of chromosomes per individual. Clarity about the role of sex chromosomes as sex determinants and their mechanisms began to emerge in the 1900s.

"The determination of sex in various living things varies, one of the most common is the presence and role of sex chromosomes. In general, every living thing, whether male or female, has the same number of chromosomes, and females are only in pairs of sex chromosomes. ," he explained. (SMH) (IAAS/FAP)
