DRAW IT A pea plant heterozygous for inflated pods (Ii) is crossed with a plant homozygous for constricted pods (ii). Draw a Punnett square for this cross to predict genotypic and phenotypic ratios. Assume that pollen comes from the ii plant.

Verified step by step guidance

1. Step 1: Identify the genotypes of the parent plants. In this case, one parent is heterozygous for inflated pods (Ii) and the other parent is homozygous for constricted pods (ii).
2. Step 2: Determine the possible gametes each parent can produce. The heterozygous parent (Ii) can produce two types of gametes (I and i), while the homozygous parent (ii) can only produce one type of gamete (i).
3. Step 3: Draw a Punnett square. This is a 2x2 grid, where each cell represents a possible offspring genotype. Label the top of the grid with the gametes from one parent and the side of the grid with the gametes from the other parent.
4. Step 4: Fill in the Punnett square. Each cell is filled by combining the letter from the top of the column with the letter from the side of the row. In this case, the possible combinations are Ii and ii.
5. Step 5: Determine the genotypic and phenotypic ratios. The genotypic ratio is the ratio of the different genotypes among the offspring, while the phenotypic ratio is the ratio of the different physical traits. In this case, the genotypic ratio is 1 Ii : 1 ii, and the phenotypic ratio is 1 inflated : 1 constricted.
