In addition to the fact that the father is the one who determines the sex of the child, there are many other problems that the child inherits from the father.
People often say “Children are not like feathers like wings” and often assume that the ratio of genetic inheritance of father and mother on a child is always 50/50.
However, except for cases where the child carries a completely dominant gene of one side, so it resembles the father or mother, there are a number of scientific studies that prove that children often resemble their father more than their mother . Detail:
A study by Dr. Corry Gellatly, working at the University of Newcastle (UK) has proven that the sex of the baby is determined by the father’s genes. Because in a man’s body there are two X and Y chromosomes, while the mother’s body has only X chromosomes.
It is the father who determines the sex of the child, not the mother.
This means that if the father’s X chromosome combines with the mother’s X chromosome, a baby girl will be produced (XX), otherwise, if the father’s Y chromosome “friends” the Mother’s X will produce a son (XY).
Thus, it is clear that the birth of a son or a daughter is entirely up to the father.
Professor Van Steirteghem, currently emeritus professor at Vrije Universiteit Brussel (Belgium), has conducted research on whether father’s fertility is inherited to sons.
The results showed that the boys who received in vitro fertilization were more likely to have low sperm quality like their fathers. Meanwhile, children who were naturally inseminated had much higher sperm counts.
This means that the father’s fertility is also passed on to his son.
According to research by Dr. Brian M. D’Onofrio, from the Department of Psychological and Brain Sciences at Indiana University (USA), although both parents can affect mental health. children’s future, but the age of the father determines many issues about the mental health of children.
In other words, children born when their fathers are 45 years old will have a higher risk of diseases such as autism, attention deficit hyperactivity disorder, psychosis, bipolar disorder, etc. children with young fathers.
The US National Center for Biotechnology Information once published a study on how parents inherit the size and position of teeth, jaw shape to their children.
However, scientists believe that the father’s genes will be stronger than the mother’s genes. So the smile, enamel, sensitivity of the father’s teeth will be passed on to the child.
Dr Beatrice Knight, who teaches at the Royal Devon and Exeter Hospital (UK), said fathers are more likely to pass on their height to their children. Specifically, the researchers contacted 1,000 families to record data on the weight and height of the parents as well as the baby’s first two years of life.
The results showed that children with tall fathers were often larger and heavier than children with short fathers.
