in pea plants, tall plant height is dominant over short plant height. if there are 200 short plants in the f2 generation from a cross that followed mendels methods, about how many plants will be tall in that generation?\n200\n300\n600\n1000

in pea plants, tall plant height is dominant over short plant height. if there are 200 short plants in the f2 generation from a cross that followed mendels methods, about how many plants will be tall in that generation?\n200\n300\n600\n1000

Answer

Explanation:

Step1: Recall Mendel's ratio

In a monohybrid cross following Mendel's methods, the phenotypic ratio of tall : short plants in the F2 generation is 3:1.

Step2: Set up proportion

Let $x$ be the number of tall plants. We have the proportion $\frac{x}{200}=\frac{3}{1}$.

Step3: Solve for $x$

Cross - multiply: $x = 3\times200$. $x=600$.

Answer:

C. 600
