Answer:
Genetic alteration probably refers to altering the DNA sequence present in the genes of chromosomes.
Explanation:
Genetic alternation occurs when the DNA of an organism gets altered due to any circumstance. Even a change in a single nucleotide can have devastating effects on the organism. It can occur due to mutations or physical factors like radiation, UV etc. Genetic alternations can be useful as well as harmful. Genetic alternation is also a source due to which variations might arise in a population and hence, it leads to biodiversity.
D) allele frequencies of some traits change in the population
Alleles can be phenotype (how they appear) and natural selection is when an organism changes in a way that helps them survive.
It can be the way their beaks are formed that gives them a better chance of catching food among other stuff (Darwin's investigation)
Or how they change their color to adapt to the sudden change in tree coloration (Pepper moths)
