Male characteristic of offspring

Postby Havoc » Fri May 06, 2005 10:11 pm

Which parent usually contributes X-linked characteristic to male offspring and which to female offsprings?

For the male offspring, all X-linked characteristics come from the mother.

For the female offspring, that duty is evenly shared between both parents.

Thank you for your prompt reply. Another question then which parent contributes gametes that would determine the gender of the offspring?

The male gamete determines sex of the offspring. Male gametes either donate an X chromosome, making the offspring female or a Y chromosome, making the offspring male.

if X comes from female and male gender - offspring is female-XX, then is during embryo development random inactivation one of X chromosome and the result is one X and Barr's body in cells
