In question 3 , the plants in the rich farmland vary in height. Some of the plants are taller than others. The same is true of the plants in the backyard. The differences in heights of the plants in the same plot of soil is best accounted for by ________ . a. genetics b. environment c. 30 percent genetics and 70 percent environment d. 70 percent genetics and 30 percent environment

Short Answer

Expert verified
The differences in heights of the plants in the same plot of soil is best accounted for by 30 percent genetics and 70 percent environment, as environmental factors have a more significant influence on the observed variations within the same plot.

Step by step solution

01

Understanding Genetics

Genetics refers to the inherited traits passed on from parent plants to their offspring through genes. These traits include potential height, growth rate, and other characteristics that affect plant development.
02

Understanding Environment

Environment refers to external factors that can influence a plant's growth and development. These include factors such as sunlight, water, soil quality, and nutrient availability. Environmental conditions can cause variation in plant heights even if they have the same genetic background. #Step 2: Evaluating the Role of Genetics and Environment in Plant Height Variation#
03

Evaluating the Role of Genetics

Genetics can contribute to variations in plant height, as different genotypes may have different potentials for height. However, it is important to note that even genetically identical plants can exhibit height differences due to the influence of environmental factors.
04

Evaluating the Role of Environment

Environmental factors can significantly influence plant height by affecting the availability of resources like sunlight, water, and nutrients. As a result, variations in environmental conditions within the same plot of soil can cause differences in height among the plants. #Step 3: Selecting the Best Option#
05

Comparing the Roles of Genetics and Environment

From our analysis, we can conclude that both genetics and environmental factors can contribute to variations in plant height. However, it's difficult to pinpoint the exact percentages of each factor's contribution. Since the exercise provides options with percentages, we can assume that it is seeking a generalized representation of the contribution of genetics and environment.
06

Choosing the Correct Answer

Based on our analysis, the most suitable answer would be: C. 30 percent genetics and 70 percent environment. This is because, even though genetics plays a role in plant height, we can see that the environment has a more significant influence on variations observed within the same plot of soil.
