1. Expected phenotypic ratio of green to white progeny: _____:_____.
Calculation of Expected Ratio (Frequency) = __________ = Total Number of (Color) Seedlings ÷ Total of All Seedlings.
To calculate the expected phenotypic ratio of green to white progeny, you will need to know the total number of green seedlings and the total number of white seedlings.
1. Determine the total number of green seedlings.
- Count the number of green seedlings in the progeny.
- Let's say you counted 60 green seedlings.
2. Determine the total number of white seedlings.
- Count the number of white seedlings in the progeny.
- Let's say you counted 40 white seedlings.
3. Calculate the expected ratio.
- Use the formula: Expected Ratio = Total Number of Green Seedlings ÷ Total Number of All Seedlings.
- In this case, the expected ratio would be: 60 ÷ (60+40) = 60 ÷ 100 = 0.6.
4. Express the ratio in the form of a fraction or colon.
- The expected phenotypic ratio of green to white progeny would be 3:2 (assuming we simplify the fraction 0.6, which reduces to 3/5).
So the expected phenotypic ratio of green to white progeny is 3:2 (or 3/5).
