Use the information given here to answer the following
questions. Feather color in budgies is determined by two
different genes that affect the pigmentation of the outer
feather and its core. Y_B_ is green; yyB_ is blue; Y_bb is
yellow; and yybb is white.

    49. Two blue budgies were crossed. Over the
        years, they produced 22 offspring, 5 of which
        were white. What are the most likely genotypes
        for the two blue budgies?
             a. yyBB and yyBb
             b. yyBb and yyBb
             c. yyBb and yybb
             d. yyBB and yybb
