Answer

Explanation:

Step1: Determine parent genotypes

The heterozygous yellow - seeded plant has genotype Yy and the homozygous green - seeded plant has genotype yy.

Step2: Fill in Punnett square

The possible gametes from the Yy plant are Y and y, and from the yy plant are y and y. When we fill the Punnett square:

  • For box 1: Y (from Yy) and y (from yy) gives Yy.
  • For box 2: y (from Yy) and y (from yy) gives yy.
  • For box 3: Y (from Yy) and y (from yy) gives Yy.
  • For box 4: y (from Yy) and y (from yy) gives yy.

Step3: Determine phenotypes

Since Y represents the dominant allele for yellow seeds and y represents the recessive allele for green seeds, Yy will have yellow seeds and yy will have green seeds.

  • Box 1 (Yy): Yellow seeds.
  • Box 2 (yy): Green seeds.
  • Box 3 (Yy): Yellow seeds.
  • Box 4 (yy): Green seeds.

Answer:

  1. Yellow seeds
  2. Green seeds
  3. Yellow seeds
  4. Green seeds
