Variations within species causes by:
Mutation- changes in the sequences of genes in DNA, are one source of genetic variation.
Gene flow
Genetic drift
Environmental factor
Random events
Sexual reproduction
Recombination

37:11 Variations within a species are caused by:
1. **Genetic Mutations**: Random changes in DNA.
2. **Genetic Recombination**: Mixing of genes during sexual reproduction.
3. **Gene Flow**: Exchange of genes between populations.
4. **Natural Selection**: Favoring of traits that enhance survival.
5. **Environmental Factors**: Influence of surroundings on gene expression.
6. **Genetic Drift**: Random changes in allele frequencies, especially in small populations.

Answer of h.w question is changes in the sequence of gene that's why variation occurs within a species
