factor (such as environment).
molecular genetics - ANSWER-The subfield of biology that studies the molecular structure and
function of genes.
mutations - ANSWER-A process in which the genetic material of a person, a plant or an animal
changes in structure when it is passed on to children, causing different physical characteristics to
