In rabbits, black fur (B) is dominant to brown fur (b) and long hair (L) is dominant to short hair (l).  Two black long haired rabbits were mated and they produced 44 total F1 progeny: 25 black, long haired progeny; 9 brown long haired progeny; 7 black short haired progeny and 3 brown short haired progeny. 

• What are the genotypes of the parents? 
• List the gametes each parent can produce
• List the four different genotypes expected among the black, long haire class of offspring. 
• Of the 25 black, long haired F1 progeny how many would you expect to be of each of the four genotypes? (Show your calculations.)
• Now you wish to determine which of the black long haired F1 progeny have genotype BBLL.  To which genotype of rabbit would you mate the black log haired rabbits in order to perform a test cross?
