3.  In guinea pigs, the allele for white hair color is recessive to the allele for black hair color.  A   
     breeder plans to cross 2 guinea pigs that will produce offspring that are 100% heterozygous 
     for the trait of hair color. 
What are the genotypes of the parents?           Parent 1:  _______________________
