What is the reason for variation at the genetic level?

Genes:

1. As DNA are made up of genes, genes are functional units of heredity.
2. The chromosome is formed of DNA, which contains numerous genes.

Reason for variation at the genetic level:

1. Every gene has a unique set of instructions for a certain function or protein coding.
2. The word genetic variety refers to the variance in the DNA sequence in each of our genomes.
3. Genetic diversity is what distinguishes us all.
4. Heredity is determined by genes.
5. Polymorphism refers to variations at the genetic level.
6. Mutation, genetic recombination, and gene immigration are all sources of genetic diversity.
7. The most frequent sort of genetic variation in humans is single nucleotide polymorphisms.
8. Genetic diversity occurs in distinct versions of genes, known as alleles.
9. In evolution, genetic variety is also crucial.
