Yellow peas

Answer 1

Let's fill out the Punnett Square for the given genotypes.

Punnett Square Setup:

• Top genotype: Gg
• Side genotype: Gg

          |   G    |   g    |
      ----------------------- 
      G   |   GG   |   Gg   |
      ----------------------- 
      g   |   Gg   |   gg   |

Genotypes in the Punnett Square:

• GG: Homozygous dominant (Green)
• Gg: Heterozygous (Green)
• gg: Homozygous recessive (Yellow)

Phenotypes:

• Green peas: GG and Gg
• Yellow peas: gg

Probability Calculation:

• Total possibilities: 4 (GG, Gg, Gg, gg)
• Green peas: 3 (GG + Gg + Gg)
• Yellow peas: 1 (gg)

Probability:

• Probability of Green peas: \( \frac{3}{4} = 75% \)
• Probability of Yellow peas: \( \frac{1}{4} = 25% \)

Summary:

• Green peas probability: 75%
• Yellow peas probability: 25%
