Match each phenotypic trait or population distribution profile on the left with its corresponding characteristic pattern of variation or graphical feature on the right.
- Human height and skin colorContinuous variation influenced by polygenes and environmental factors
- ABO blood group and tongue rolling abilityDiscontinuous variation controlled by monogenic inheritance with minimal environmental effect
- Bell-shaped frequency curveGraphical representation showing a continuous spectrum of intermediate phenotypes
- Discrete bar chart with clear gapsGraphical representation showing non-overlapping, distinct phenotypic categories
Answer
Human height and skin color matches with Continuous variation influenced by polygenes and environmental factors. ABO blood group and tongue rolling ability matches with Discontinuous variation controlled by monogenic inheritance with minimal environmental effect. Bell-shaped frequency curve matches with Graphical representation showing a continuous spectrum of intermediate phenotypes. Discrete bar chart with clear gaps matches with Graphical representation showing non-overlapping, distinct phenotypic categories.
Human height and skin color exhibit continuous variation caused by polygenic inheritance and environmental influences. ABO blood group and tongue rolling ability show discontinuous variation controlled by single genes with minimal environmental impact. Population data for continuous variation forms a smooth bell-shaped curve showing intermediate phenotypes, whereas discontinuous variation forms a discrete bar chart with distinct non-overlapping categories.
