The textbook illustration of mixed seeds growing in different soils demonstrates that __________.
A) genetic differences between groups can be directly assessed
B) high within-group heritability means that between-group differences are also genetically determined
C) within-group differences and between-group differences may be caused by separate factors
D) different environments tend to produce the same amount of within-group variability

Question

Quizplus · Accepted Answer

The illustration of mixed seeds growing in different soils suggests that within-group differences and between-group differences may be caused by separate factors, as the same types of seeds exhibited different growth patterns in different types of soil. This suggests that environmental factors play a role in shaping differences between groups. It does not necessarily provide direct evidence of genetic differences between the groups (choice A) or high within-group heritability (choice B), nor does it suggest that different environments produce the same amount of within-group variability (choice D).
