Question

Two plants are grown under the same environmental conditions, including the same soil conditions and the same amount of light and water, but one grows to 2 feet tall and the other is 1 foot tall. In this case, the heritability would be closest to

a. 5 percent
b. 25 percent
c. 50 percent
d. 80 percent
e. 95 percent

Answer 1

In this case, the heritability would be closest to 25 percent. Heritability refers to the proportion of variation in a trait that can be attributed to genetic factors.

Step-by-step explanation:

In this case, the heritability would be closest to b. 25 percent.

Heritability refers to the proportion of variation in a trait that can be attributed to genetic factors. In this scenario, the plants are grown under the same environmental conditions, indicating that any difference in height is more likely due to genetic factors. The fact that one plant grows to 2 feet tall and the other grows to 1 foot tall suggests there is genetic variation between the plants.

The heritability percentage represents the extent to which differences in height between the plants can be attributed to genetics. With 25 percent heritability, genetic factors account for 25 percent of the variation in height between the plants, while the remaining 75 percent is likely due to non-genetic factors such as environmental conditions.
