The child’s gender is based on inheritance, a new study suggests

When a new member is about to arrive in the family, the first thing that excites us the most is if it will be a girl or a boy. If you too are super excited to know your baby’s gender, this study can definitely give you a hint!

the study

A new research paper published by the University of Newcastle in England has revealed that the father’s genes determine whether you will have sons or daughters.

The study included an analysis of 927 family trees that date back to the year 1600. By now, scientists have understood that the sex of a baby can be determined as follows: if the sperm carries an X or Y chromosome and attaches to the mother’s X chromosome. To make XX (baby girl) or XY (baby boy).

According to a new Newcastle study, an unnamed gene regulates a man’s ratio of X and Y sperm, making them more likely to have a baby boy than others.

The family tree states that the sex of the child is based on inheritance. If the father has more brothers, then he is more likely to have a son, while if he has more sisters, the girl is more likely to come.

The study explains why there is a balanced ratio between male to female births. A scientist from the Newcastle team said, “If there are too many males in the population, females will more easily find a mate, so males with more daughters will pass on their genes more, producing more females in later generations”.

But now that sibling sets are limited to small pools, it can be difficult to get any definite information from the gender of a person who has one or two siblings.

And even when you know that a man is more likely to have a daughter, according to this theory, there is always a room for variance.
