how can paired chromosomes differ?

PLEASE HELP ME!!!

Each of the paired chromosomes are received one from the father and the other from the mother. They reflect their own personal genetic makeup. That's how they can differ.

I hope this helps. If not, please repost with any questions that might be raised. Thanks for asking.

THANK YOU SOOO MUCH! SORRY ABOUT MY LAST POST I DIDN'T NOTICE YOU ANSWERED THIS POST
