Question

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?
200
300
600
1,000

Explanation:

Step1: Record the phenotypic ratio

En los experimentos de Mendel, el ratio fenotípico en la generación F2 de un cruce monohíbrido (altura de planta) es 3 (altos) : 1 (bajos).

Step2: Establecer una proporción

Sean \(x\) el número de plantas altas. Sabemos que \(\frac{x}{200}=\frac{3}{1}\).

Step3: Resolver la proporción

Multiplicando ambos lados por 200: \(x = 3\times200=600\).

Answer:

C. 600
