Allopatric Speciation or/and Sympatric Speciation! :)
Answer:
Blue offspring only
Explanation:
If A blue budgie is crossed with a white budgie.
i.e yyBB or yyBb × yybb
let use yyBb for blue budgie,so we have; yB, yb, yB, yb representing the columns on the horizontal rows of the punnet square.
on the other hand, in white budgie yybb, we will have yb, yb, yb, yb representing the rows on the vertical column of the punnet square.
if a dihybrid cross occurs among these representative, all progeny in the punnet square will be yyBb, showing that they are all Blue offspring only.
