Here is the complete 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, YYBb or YyBb is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white. A blue budgie is crossed with a white budgie. Which of the following results is possible?

A.) Yellow offspring only.

B.) Blue and white offspring.

C.) a 9:3:3:1 ratio

D.) Green offspring only.

E.) Green and yellow offspring

B.) Blue and white offspring.

Step-by-step explanation:

Given that;

Genes exhibiting Green color are ⇒ YYBB, YyBB, YYBb or YyBb

Genes exhibiting Blue color are ⇒ yyBB or yyBb

Genes exhibiting Yellow color are ⇒ YYbb or Yybb

Gene exhibiting White color ⇒ yybb

If we have a blue budgie cross with a white budgie; we will have the following offsprings as illustrated below:

yyBB or yyBb × yybb

Let take yyBb × yybb for example;

if yyBb self crosse; we have: (yB, yb, yB, yb)

if yybb self crossed; we have : (yb,yb, yb, yb)

In a dihybrid cross; the following is shown below for the above traits.

yB yb yB yb

yb yyBb yybb yyBb yybb

∴ we have 8/16 yyBb (blue) and 8/16 yybb (white) offspring.

= 1/2 (blue) and 1/2 (white) offspring.

Therefore, the cross between a blue budgie and white budgie produces blue and white offspring.
