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 mendel’s methods, about how many plants will be tall in that generation?\n○ 200\n○ 300\n○ 600\n○ 1,000

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 mendel’s methods, about how many plants will be tall in that generation?\n○ 200\n○ 300\n○ 600\n○ 1,000

Answer

Explanation:

Step1: Recall Mendel's ratio

For a monohybrid cross (tall vs short in pea plants), the F2 generation ratio of tall to short is 3:1 (dominant:recessive).

Step2: Let number of short plants be ( s = 200 ), tall plants be ( t ).

From ratio ( \frac{t}{s}=\frac{3}{1} ), so ( t = 3\times s ).

Step3: Substitute ( s = 200 )

( t = 3\times200 = 600 ).

Answer:

600
