MCQ
The material for organic evolution is:
- AEffect of hormones
- BNutritive value
- CMutation
- DAsexual reproduction
Explanation:
Mutation is sudden, discontinuous variation in genotype and phenotype of an organism due to change in chromosomes and genes.In addition to recombination, mutation is another phenomenon that leads to variation in DNA. A point mutation is a change of a single base pair in DNA.Some mutations involve changes in the whole set of chromosomes (polyploidy) or change in a subset of chromosome number (aneuploidy). So, the material for organic evolution is mutation because mutation leads to evolution.
