Hi Christina,

Gray whales produce a single calf which is usually born in the winter. 
Like most baleen whales, they migrate seasonally so they are in warm
waters to calve and colder waters to feed. Again, like most baleen
whales, gray whales mate promiscuously (many each individual mates with
amny others and no pair bonds are formed).  Mating also occurs in the
winter.  For more info, try the sites below.

Your best bet for diagrams is off the wrote:

good luck!
