Why is the ratio of male to female births roughly 50:50? help me please!!!

lina2011 [118]

Answer:

This is because of how reproduction works in humans. Male and female sex cells are formed by a process called meiosis, where the diploid chromosomes divide and separate. And so the ratio of male to female births is also 50:50.
