Subject: Since the Egg 'lets' in a sperm, isn't sex determined by the female?

Henry VIII decapitated Ann Bolin because she did not produce a male heir to the 
throne, the Jesuit Mendol showed the male carries the gene to determine sex of 
the offspring.  Since hundreds of sperm reach the egg and the egg allows only 
one to enter and not always the first can we finally conclude the Henry was 
right? ie that the female may play the major role to determine the sex of the 
offspring?
