Genetic Variants- different forms of the same gene

mutations are changes to the genome, its a rare random change in an organisms DNA that can be inherited

mutations mean that the sequence of DNA bases in the gene are changed, which produces a genetic variant

as the sequence of DNA bases in a gene code for the sequence of amino acids that make up a protein, gene mutations sometimes lead to changes in the protein that it codes for.

most genetic variants have very little or no effect on the protein the gene codes for 

some will change it to s small extent that its function is unaffected, this means the mutations have no affect on an organisms phenotype

some variations ahve a small influence on the organisms phenotype, they alter the organisms characteristics but only slightly

for example

eye colour are controlled by more than one gene, a mutation in one of the genes may change the…
