<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
<u>Cross for T gene</u>
Parental ) Tt x Tt
Gametes) T t T t
Punnet square) T t
T TT Tt
t Tt tt
F1) Genotypic proportion 1/4 TT
2/4 Tt
1/4 tt
Genotypic ratio 1 : 2 : 1
Phenotypic proportion: 3/4 T-
