The Washington Linkage Group supports the statement "We hold these truths to be self-evident, that all men are created equal..."
The statement "We hold these truths to be self-evident, that all men are created equal..." (US Declaration of Independence, 1776) reflect morality, not science. One can accept this moral imperative and still recognize that all individuals, independently conceived, are genetically unique.
In government, all men created equal as all men receive equal opportunity and consequence.
In genetics, linkage group are all of the genes on a single chromosome. They are inherited as a group; that is, during cell division they act and move as a unit rather than independently. The existence of linkage groups is the reason some traits do not comply with Mendel’s law of independent assortment (recombination of genes and the traits they control); i.e., the principle applies only if genes are located on different chromosomes.
Variation in the gene composition of a chromosome can occur when a chromosome breaks, and the sections join with the partner chromosome if it has broken in the same places. This exchange of genes between chromosomes, called crossing over, usually occurs during meiosis, when the total number of chromosomes is halved.
