While the number of men and women has been almost the same, families who have kids of only one gender always leave people wondering why this happens. 60% of parents in the US have more than one child, and many people are scratching their heads about why they have multiple children of the same gender and how they can possibly have a boy or a girl.
We at Bright Side were curious about the reason behind this phenomenon and if a family who had only boys or only girls for generations could give birth to a kid of another gender.
1. It’s impossible to have an undiscovered “daughter” or “son” gene.
While most families have an imbalanced sex ratio, other parents can’t conceive boys or girls, and some even believe that girl or boy genes “run the family.” But researchers still haven’t found any shred of evidence that proves if some families can have only males or females because of their genes. At some point, scientists might change their opinion, but as for now, there’s no way your family’s genes can have an effect on whether you’ll have kids of only one gender.
