Answer and Explanation:

cross: BbTt x bbTt

<u>Cross for B gene</u>

Parental ) Bb   x   bb

Gametes) B   b   b   b

Punnet square)  B     b

                  b     Bb    bb

                  b     Bb    bb

F1) Genotypic proportion: 2/4=1/2 Bb : 2/4=1/2 bb

     Genotypic ratio 1:1

     Phenotypic proportion: 2/4=1/2 B- : 2/4=1/2 bb

     Phenotypic ratio   1:1
