Hi!
Soon we will be able to test this theory.................... We have one girly already.
"Although the sex ratio averages out everywhere to 105 boys for every 100 girls, researchers have found that men in some occupational groups have a tendency to have more girls. Some studies have found that pilots, astronauts and deep sea divers have more girls. The Y chromosome is more fragile than the X chromosome - one theory is that the huge temperature and pressure changes experienced by divers and pilots can harm the genetic composition of the Y DNA, killing them off and meaning that the X's are more dominant. Hence a daughter is more likely!"
