Question

If the generation time of silkworm is about 4 weeks, which of the following hypotheses offers the best explanation for the difference in silk productivity between the two colonies?

a) Differences in feeding habits
b) Genetic variations
c) Environmental conditions
d) Differences in cocoon structure

Answer 1

The best hypothesis that offers an explanation for the difference in silk productivity between the two colonies of silkworms is genetic variations.

Step-by-step explanation:

The best hypothesis that offers an explanation for the difference in silk productivity between the two colonies of silkworms is b) Genetic variations. Genetic variations can affect various traits, including silk productivity, in organisms. Different genetic variations in the two colonies could result in differences in the quality or quantity of silk produced. For example, one colony may have genetic variations that allow for the production of stronger silk or a higher silk yield.
