Suppose D were dominant and d were recessive,and you could label the D allele in the P generation with a radioactive substance that could be inherited over several generations.You create hybrids by mating your radioactive DD individuals to dd individuals.Finally,you cross two Dd individuals.In 1,000 offspring,how many do you predict would be radioactive?
A) 250
B) 500
C) 750
D) 1,000
