which type of chromosome does the female parent give to its offspring
XY sex-determination system In humans, half of spermatozoons carry X chromosome and the other half Y chromosome.[3] A single gene (SRY) present on the Y chromosome acts as a signal to set the developmental pathway towards maleness. Presence of this gene starts off the process of virilization. This and other factors result in the sex differences in humans.[4] The cells in females, with two X chromosomes, undergo X-inactivation, in which one of the two X chromosomes is inactivated. The inactivated X chromosome remains within a cell as a Barr body.
