Question
During a class on sexual reproduction, the instructor asked how many sex chromosomes does a neuron have?  I thought all cells in the body had a copy of all chromosomes, but after this question, I am beinging to have doubts.  Please help me understand this thought so I can determine the answer to the question.

Answer
Hi Adam:  Thanks for your question.

Yes, all the cells of the body (except the gametes) have the same number of chromosomes.  So a neuron, stomach, bone, etc cell would each have 46 chromosomes (in a human!).  They would have two X's if the individual were a female, and XY if a male.


Hope this helps!
