Question

the genotype ratio for this punnett square is ____, and the phenotype ratio is ____.
y
g
y
yy
yellow
yg
yellow
g
yg
yellow
gg
green

Explanation:

Step1: Count Genotypes

Identify each genotype: YY (1), Yg (2), gg (1). So genotype counts: YY:1, Yg:2, gg:1. Ratio is \(1:2:1\) (YY:Yg:gg).

Step2: Count Phenotypes

Phenotypes: yellow (YY, Yg, Yg) → 3, green (gg) → 1. Ratio is \(3:1\) (yellow:green).

Answer:

Genotype ratio: \(1:2:1\) (YY:Yg:gg); Phenotype ratio: \(3:1\) (yellow:green)
