In which way does epigenetic change alter the development of a given person's phenotype?
A)It influences gene expression,the process by which DNA forms proteins that contribute to the features of living cells.
B)It inhibits the ability of a sperm cell and an egg cell to correctly "match" each of the 23 gene pairs,leading to chromosomal distortions.
C)It enhances the "strength" of recessive or mutated genes,so that they can no longer be masked by dominant alleles of the same gene.
D)It increases the likelihood that specific genes will work in singular form to cause a specific phenotype.

Epigenetic changes can alter gene expression, which directly affects the proteins that are formed by DNA. This can lead to changes in the development of a person's phenotype. Epigenetic changes can be caused by factors such as environmental stimuli, developmental programming, and hereditary factors. These changes can occur without any changes in the underlying DNA sequence, thus providing an additional layer of complexity to genetic regulation. Epigenetic changes can be passed on from one generation to the next, which may contribute to the heritability of certain traits and diseases.
