Question

How do you differentiate between qualitative and quantitative traits?

a) By their underlying genetic complexity
b) Based on their mode of inheritance
c) Through their response to environmental factors
d) According to the number of involved genes

Answer 1

Qualitative traits are controlled by a single or a few genes, resulting in distinct phenotypes. Examples include eye color or blood type. Quantitative traits are controlled by multiple genes and their expression varies along a continuous spectrum.

Step-by-step explanation:

Qualitative traits and quantitative traits can be differentiated based on the number of involved genes. Qualitative traits are controlled by a single or a few genes, resulting in distinct phenotypes. Examples of qualitative traits include eye color or blood type. On the other hand, quantitative traits are controlled by multiple genes, and their expression varies along a continuous spectrum. Examples of quantitative traits include height or weight.
