Mating between relatives is called which of the following?
Correct answer: A. Inbreeding
- A. Inbreeding
- B. Ex breeding
- C. Breeding
- D. Outbreeding
Explanation
The correct answer is Inbreeding. Inbreeding is the mating between relatives, which can lead to a higher probability of offspring inheriting two copies of a recessive gene, potentially leading to genetic disorders. Option A is correct because it accurately describes this process. Option B is incorrect because it refers to an undefined term. Option C is too general and does not specify the type of mating. Option D is incorrect because it describes mating between unrelated individuals, which is the opposite of inbreeding.

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.
