[QUOTE="Keren, post: 398455, member: 3195"] That is correct. The cow produces gametes that are all X (because she is XX). The bull however is XY so half his sperm cells carry the X and the other half carry the Y. This is why they are able to seperate them and create 'sexed semen'. X sperm will produce XX - heifers and Y sperm will produce XY - bulls. [/QUOTE]
