6. Let us suppose that a vertebrate organism carries a mutation that causes some cells that normally differentiate into nerve cell to differentiate into muscle cells. A molecular analysis reveals that this mutation is in a gene that encodes a DNA methyltransferase. Explain how an alteration in a DNA methyltransferase could produce this phenotype.

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
