Although the number of women and men is largely the same, families with children of the same sex always wonder why this happens. About 60% of parents in the U.S. have more than one child, and many scratch their heads about why they have a majority of children of the same sex and how they can have a boy or a girl.
1. It is not possible to have an undiscovered “daughter” or “son” gene.
Many families have unbalanced sex ratios, while other parents cannot conceive boys or girls, with some believing that the female or male genes are “family-run.” But researchers have not yet found any evidence that some families are genetically predisposed to males or females. At some point, scientists may change their minds, but for now, your family’s genes may not affect whether you have children of just one gender.
2. Gender is determined by the father.
Some believe that the gender of a child depends on the mother and that she carries it because she is, in fact, in the hands of the father. Some sperm carry X chromosomes for girls, and others carry Y chromosomes for boys, as sperm carry chromosomes to both sexes. A woman carries two chromosomes, and the sex of a newborn depends on the number of sperm (X or Y) that enters the female egg.
3. Female babies are more common during times of stress.
However, scientists have discovered several factors that can affect gender. It has been proven that the sex ratio changes after stressful times such as natural disasters and more newborn girls. This may be due to the stress that future mothers are exposed to.
4. Eating special foods makes a girl more likely to have.
Especially, eating certain foods has been shown to increase a girl’s chances of conceiving. For example, reducing salt intake and consuming plenty of dairy products increase the chances of having a baby girl. On the other hand, rich in sodium and potassium-rich foods are more likely to give birth to boys.
5. It’s just a coincidence that a mother usually has children of the same sex.
It is well known that the gender balance has remained the same for centuries, and there are no areas where it can be significantly changed. Families with many children of the same sex are rare but can be explained statistically. Every child has a 50% chance of becoming a boy or a girl. For example, for three children, the chance that they would all be male: 0.5 X 0.5 X 0.5 = 0.125, or 12.5%.
