The science of genetics informs us that you are what you are largely as a result of twenty-four chromosomes contributed by your father and twenty-four chromosomes contributed by your mother. These forty-eight chromosomes comprise everything that determines what you inherit. In each chromosome there may be, says Amram Scheinfeld, “anywhere from scores to hundreds of genes—with a single gene, in some cases, able to change the whole life of an individual.” Truly, we are “fearfully and wonderfully” made.
