my june 99 got 20-30 missing..lool
well..apparently..the answer is y-chromosome..X-Y are neither genes, nor alleles..we consider them chromosomes..and in additon..every bod cell has XY chromosome..which means..it always has X and alwas has Y chromosome.

haha weird!
thanks alot
nid404:
hey Kim,
sorry for the delay but insanity-stricken has correctly said Y chromosome
Remember in females it's XX and males it's XY
so the sex is determined by this
Only if the Y chromosome from the male combines with the females X chromosome will a boy be born
If X chromosomes from both combine it will be a girl
@ insanity-stricken: thanks for answerin it
