Question
__________ is the degree to which differences are seen between parents and their offspring.
- Variation
- Mutation
- Recombination
- Reproduction
Hint:
Parents and offspring belong to same species but have difference in their genetic make up.
The correct answer is: Variation
- Variation causes the difference in the genetic sequence between individuals of the same species.
- The parents and offspring belong to same species with same number of chromosomes, but the sequence of arrangement of the nucleotides will be different. This is due to sexual reproduction, wherein the zygote formed has a combination of both the parents chromosomes.
- The gametes are formed by meiosis during which several processes like independent assortment, crossing over will occur, resulting in genetic variation.
