Explanation:
Detailed explanation-1: -Sometimes the environment changes a gene-either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits. Some harmful environmental factors can change a gene’s nucleotide sequence. For example, UV radiation can break DNA strands.
Detailed explanation-2: -Heritability estimates range from zero to one. A heritability close to zero indicates that almost all of the variability in a trait among people is due to environmental factors, with very little influence from genetic differences.
