If a plant with genotype Aa is crossed with a plant with genotype aa, what is the expected phenotypic ratio of the offspring?

If a plant with genotype Aa is crossed with a plant with genotype aa, what is the expected phenotypic ratio of the offspring?

Step 1: Identify the genotypes of the parent plants. One plant has genotype Aa and the other has genotype aa.
Step 2: Write down the possible gametes (sex cells) each parent can produce. The Aa plant can produce gametes A and a, while the aa plant can only produce gametes a.
Step 3: Set up a Punnett square to visualize the cross. Place the gametes from one parent on the top and the gametes from the other parent on the side.
Step 4: Fill in the Punnett square by combining the gametes. The combinations will be Aa (from A and a) and aa (from a and a).
Step 5: Count the resulting genotypes from the Punnett square. You will have 1 Aa and 1 aa.
Step 6: Determine the phenotypes based on the genotypes. Aa will show the dominant trait (A) and aa will show the recessive trait (a).
Step 7: Calculate the phenotypic ratio. You have 1 plant showing the dominant trait (Aa) and 1 plant showing the recessive trait (aa), resulting in a 1:1 ratio.
