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?\no 200\no 300\no 600\no 1,000

Answer

Explanation:

Step1: Recall Mendelian ratio

In a monohybrid cross following Mendel's laws, the phenotypic ratio of the F2 generation is 3:1 (tall:short).

Step2: Set up proportion

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

Step3: Solve for $x$

Cross - multiply: $x = 200\times3$. $x=600$.

Answer:

600
