Question

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 yyBBb. yyBB and yybbc. yyBB and yyBbd. yyBb and yybbe. yyBb and yyBb

Answer 1

e. yyBb and yyBb

Step-by-step explanation:

The blue budgies have the genotype either yyBB or yyBb. After their cross they produced some of the white offspring. This means that in their genotypes must be recessive alleles (because white genotype is yybb). So the genotypes of the "parents" are: yyBb and yyBb.
