Now a new research has come to the fore regarding how the sex of the unborn baby is determined. This new research done at Duke University shows that the sex of the child growing in the womb is determined by the hot temperature. According to research, the capacity of egg production of female category increases in hot temperature. At present this experiment has been done on turtles .
In the world of scientists, this discovery is being said to be very important. Scientists have tried this discovery not only on turtles but also on other species, and the results have been shocking. Among them too, high temperature was found to determine the female gender to the maximum.
How does temperature determine sex determination?
According to the researchers , higher incubation temperatures lead to a rapid increase in the number of embryo-bearing germ cells (pre-egg conditions) and the germ cells themselves start adopting the process of becoming female due to heat.
According to author Blanche Capel, professor of cell biology at Duke School of Medicine, temperature is a mechanism for sex determination. High temperature has a cascading effect that affects sex determination sequentially through many types of cells in the embryo.
How is the female gender formed in the womb?
According to Boris Tezak, the researcher who led this investigation, the female penis is formed from abundant germ cells. Although scientists say that not only sex determination but also sexual development depends on temperature, this is not a hidden fact, they have known this for years. This has been observed in various walks of life. But according to the researchers, it is important to know why this happens in case of change in weather and climate change.
According to scientists, a female that lays eggs with more germ cells is probably more suitable for reproduction. And it is determined by the high temperature. This increases her fertility to lay more eggs. By the way, this method can prove to be very helpful in understanding why sexual development depends on temperature.
What will be the effect of global warming?
Now important questions are arising that as the earth is getting warmer, the risk of global warming is increasing, what will be its effect on species like turtle? Will their fertility increase on their own? Researchers want to investigate this.
According to the scientist, the embryo inside the egg develops due to the heat of the light. Researchers say that during the experiment they kept some eggs at a temperature of 33.5 degrees, which was only two and a half degrees higher than the temperature required for females. Then he saw the formation of some strange types of embryos. There were cyclops and two-headed fetuses. This result was shocking.
Experiments were also done on crocodile and fish
In addition to turtles, scientists at Duke University have also done this kind of experiment on alligators and fish. The special thing is that similar experiences were seen in fish as in turtles, but some different results were seen in crocodiles.
According to scientists, crocodiles produce females at low temperature and males at high temperature, it is opposite to turtle or fish. But interestingly, the low temperature of crocodiles is also similar to the high temperature of turtles, both species produce females at 31 °C.
