Compare and contrast discontinuous and continuous variation using human blood groups and height as examples.

You're on a roll — Here are the differences between the type of variation in human blood groups and height: Blood Groups (Discontinuous Variation): Shows distinct categories* with no intermediate values (e.g., A, B, AB, O). Is qualitative* (either you have it or you don't). Is controlled by one or a few genes* (monogenic/oligogenic). Is not significantly affected by environmental factors*. Height (Continuous Variation): Shows a range of intermediate values* between two extremes. Is quantitative* (can be measured). Is controlled by many genes* (polygenic inheritance). Is significantly affected by environmental factors* (e.g., nutrition, health). What's next? 📸
