thats what turhtle said!!! you guys said turhtle was wrong

Answer 13

It's A because there are 12 pairs of the chromosomes but 1 X left over for another X or Y to join it. XY if it's a BOY and XXfor girl.

Answer 14

DeadTurtle - yes, the answer is A. But *not* from 12 pairs and one sex chromosome.

Sex chromosomes contain *one copy only* of each chromosome. It is the somatic cells, the ordinary body cells like bone and muscle, that contain two copies of each chromosome and two sex chromosomes.

Answer 15

thats what turhtle was saying!!!!! OMG

Answer 16

No, it wasn't what Turtle said. Turtle said "12 pairs" when in fact there are 22 unpaired chromosomes. Besides, 12 pairs would be 24 chromosomes. It is a very, very important distinction.
