Will you have a boy if no equals morning sickness in the first trimester?
Scientifically, the gender of a baby is determined by the presence or absence of a Y chromosome. If the sperm carrying the Y chromosome fertilizes the egg, the baby will be biologically male. If the sperm does not carry the Y chromosome, the baby will be biologically female. Therefore, the sex of a baby is determined at the moment of conception and is unrelated to the mother's experience of morning sickness.
