But when it comes to what determines the sex of a baby, only two of those chromosomes in that initial cell play a role The interplay of these specific chromosomes governs the initial developmental path At the moment of fertilization, one chromosome from the sperm and one from the egg determine the sex of the baby.
Medical researchers have made a new discovery about how a baby's sex is determined A baby’s sex is determined at conception, but sex organs develop later on, particularly between weeks 7 and 12 of pregnancy. Learn about how genetic traits determine the sex of your baby, including which parent ultimately determines the sex and when you can find out the gender. How biological sex is determined to understand how a baby's sex develops in the womb, it helps to start with the basics of genetics and the sex determination system
Endocrinologist lisa becht explains that in many species, including humans, chromosomes determine sex. This genetic arrangement determines a baby’s sex at conception
