🤓 Based on our data, we think this question is relevant for Professor McCleary's class at USF.
Feather color in budgies is determined by two different genes Y and B, one for pigment on the outside and one for the inside of the feather. YYBB, YyBB, or YYBb is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white.
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
e. yyBb and yyBb
