Why Some Women Give Birth Only To ʙᴏʏs Or Only To ɢɪʀʟs, According To Science

While the number of men and women has been almost the same, families who have kids of only one ɢᴇɴᴅᴇʀ always leave people wondering why this happens. 60% of parents in the U.S have more than one child, and many people are scratching their heads about why they have multiple children of the same ɢᴇɴᴅᴇʀ and how they can possibly have a ʙᴏʏ or a ɢɪʀʟ.

If a family who had only ʙᴏʏs or only ɢɪʀʟs for ɢᴇɴᴇʀᴀᴛɪᴏɴs could give birth to a kid of another ɢᴇɴᴅᴇʀ.

1.ɢᴇɴᴅᴇʀ is determined by the father.

While some people believe that a child’s ɢᴇɴᴅᴇʀ depends on the mother becaU.Se she’s the one that carries it, in reality, it’s in the father’s hands. Since sᴘᴇʀᴍ ᴄᴀʀʀɪᴇs ᴄʜʀᴏᴍᴏsᴏᴍᴇs for both ɢᴇɴᴅᴇʀs, some spermatozoa carry X ᴄʜʀᴏᴍᴏsᴏᴍᴇs for ɢɪʀʟs, while others carry Y ᴄʜʀᴏᴍᴏsᴏᴍᴇs for ʙᴏʏs. While a woman carries 2 X ᴄʜʀᴏᴍᴏsᴏᴍᴇs, the ɢᴇɴᴅᴇʀ of a newborn depends on which sᴘᴇʀᴍᴀᴛᴏᴢᴏᴏn (X or Y) enters the Fᴇᴍᴀʟᴇ ᴇɢɢ.

2.It’s impossible to have an undiscovered “ᴅᴀᴜɢʜᴛᴇʀ” or “sᴏɴ” ɢᴇɴᴇ.


While most families have an ɪᴍʙᴀʟᴀɴᴄᴇᴅ sᴇx ʀᴀᴛɪᴏ, other parents can’t conceive ʙᴏʏs or ɢɪʀʟs, and some even believe that ɢɪʀʟ or ʙᴏʏ ɢᴇɴᴇs “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 ɢᴇɴᴇs. At some point, scientists might change their opinion, but as for now, there’s no way your family’s ɢᴇɴᴇs can have an effect on whether you’ll have kids of only one ɢᴇɴᴅᴇʀ.

3. Eating specific food may lead to higher chances of having a ɢɪʀʟ.

It’s been proven that eating certain foods increases the chances of conceiving a ɢɪʀʟ. For example, cutting down on salt and eating plenty of dairy products might increase the chances of having a baby ɢɪʀʟ. On the other hand, mothers whose diets are full of food rich in sodium and potassium are more likely to give birth to ʙᴏʏs.

4.In times of sᴛʀᴇss, Fᴇᴍᴀʟᴇ babies are more common.

However, scientists have found some factors that might influence ɢᴇɴᴅᴇʀ. It has been proven that after sᴛʀᴇssful times, like natural ᴅɪsᴀsᴛᴇʀs, the sᴇx ratio will change, having more newborn ɢɪʀʟs. It might be due to the sᴛʀᴇss future mothers have been exposed to.

5.Usually if a mother has kids of only one ɢᴇɴᴅᴇʀ, it’s just a coincidence.

It’s known for sure that ɢᴇɴᴅᴇʀ balance has stayed the same for centuries, and there are no aspects that can significantly change it. Families who have many kids of the same ɢᴇɴᴅᴇʀ are rare but can be explained statistically. Each child has a 50% chance of being a ʙᴏʏ or a ɢɪʀʟ. So, for example, for 3 children, the chance of all of them being male is: 0.5 X 0.5 X 0.5 = 0.125, or 12.5%.
