    Yeah the Y chromosome doesn’t kick in until later in fetal development.

    There’s actually a surprisingly small amount of biological information stored on the Y chromosome, IIRC the vast majority lies on the X.

      There’s only around 700 genes in the Y chromosome, with only about 70 actually making proteins. Compare the X chromosome with about 800 protein-coding genes and 20-25,000 total genes.
