Phenotype ratio= All red

b. Genotype ratio= 1/2 Bb: 1/2 bb

Phenotype ratio= 1/2 red: 1/2 silver black

c. Genotype ratio= All Bb

Phenotype ratio= All red

Explanation:

a. pure red x carrier red:

Genotype of parents: pure red (BB) x carrier red (Bb)

Genotype ratio of progeny= 1/2 BB: 1/2 Bb

Phenotype ratio of progeny= All red

b. carrier red x silver-black

Genotype of parents: carrier red (Bb) x silver-black (bb)

Genotype ratio of progeny= 1/2 Bb: 1/2 bb

Phenotype ratio of progeny= 1/2 red: 1/2 silver black

c. pure red x silver black

Genotype of parents: pure red (BB) x silver black (bb)

Genotype ratio of progeny= All Bb

Phenotype ratio of progeny= All red
