If an individual does not reproduce then it's degree of fitness is?
Correct answer: D. 0%
- A. 100%
- B. 50%
- C. 40%
- D. 0%
Explanation
Option D is correct because, in evolutionary biology, fitness is defined by an individual's ability to pass on its genes through reproduction. If an individual does not reproduce, its fitness is considered to be 0%, as it contributes no offspring to the next generation.Option A is incorrect because a fitness level of 100% indicates the highest reproductive success, which is not applicable here.Option B is incorrect because a fitness level of 50% implies some level of reproduction, which is not the case for an individual that fails to reproduce.Option C is incorrect because a fitness level of 40% signifies some reproductive success, which does not apply to an individual with no reproduction.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
