Is fetal sex related to mother's character? Mothers are more likely to have boys when they are extro

According to a British study, extroverted women are most likely to have boys. So the sex of the baby depends not only on the father's chromosome, but also on what factors?

And the more a woman feels she will live longer, the more likely she is to have a boy in her first child.

In response, Dr. Johns of the UK Office believes that 'the link between the age of expected longevity and the sex of a woman's first child can be attributed to a selfish act of human genes'.

Dr. Johns said that many research results clearly show that the sex of the fetus is related to the character of the mother.

However, he added: 'the results of this study do not mean that women can change the gender of their first child by changing their perspective on the future '

So why do outgoing women tend to have boys?

To this end, evolutionary biologists, this phenomenon is known as the 'Trivers Willard hypothesis':

When a mother lives under great pressure of life, she is in poor health, poor living conditions and lack of food. Then, the biological induction in her body will make her give birth to a girl, not a boy.

As for the reason, it may be that girls spend less energy and material resources than boys?!

As for the relationship between the sex of the fetus and the personality of both parents,

Statistics of relevant departments in China show that:

I. both husband and wife, one is extraverted and the other is introverted, so they are 50% more likely to have girls

2. Both husband and wife are introverted, so their chances of having a girl are 0.

Third, both husband and wife are extroverted. The probability of having a girl is 100%.

4. If the husband and wife are extroverted and neutral, the probability of having a girl is 70%.

5. Both husband and wife, only the female is extroverted, and the probability of having a boy is 80%.

At present, Hong Kong gene testing center has launched ntad23 non-invasive prenatal testing in Hong Kong. During the activity, it only needs 4500 Hong Kong dollars to test the most comprehensive fetal chromosome gene testing technology in the world, such as fetal malformation, chromosome disease, family genetic history, etc., which can be detected. At present, more than 80% of pregnant women in China will choose to do prenatal non-invasive testing.
