Answer to your Health Question


Question:

I have just found out that I am pregnant although only 6 weeks. I already have 1 girl the oldest followed by 4 sons. I would love it to be a little girl but what is the probability of that happening after 4 sons?

Louisa

 

Answer:

Dear Louisa,

The probability of a female infant appeared unrelated to the genders of the preceding siblings.

The sex ratio of 1.06 (or 1.05) 51.4% male remains constant in USA.

There is no evidence of variation with maternal age .

There is no evidence that mothers with sons are more likely to continue than those with daughters.

There is no evidence to suggest that gender determination is anything other than a chance process.

Your probability of having a girl is 48.6%.
