Chances of having a boy or a girl? DH has 5 brothers but my FIL has 4 sisters?

Question

Genetically is there always a 50/50 chance of either s*x or do you have more of a chance of having a boy if there are more boys in the family? Are there any good websites about this?

It's been a while since I took biology and learned about genetics...

Answer 1

i believe the male sperm is faster than the female but female is stronger and last longer. good luck!
