Kin selection is not the same thing as group selection, where natural selection acts on the group as a whole.

This enzyme belongs to the FAD dependent oxidoreductase family, and acts on the CH-NH group of D-amino acid donors with oxygen as acceptor.

This enzyme belongs to the family of oxidoreductases, to be specific those acting on the CH-OH group of donor with other acceptors.

The center of the infinite-dimensional unitary group U() is, as in the finite dimensional case, U(1), which again acts on the unitary group via multiplication by a phase.

Let be an abelian noncyclic group acting on the finite group Assume that the orders of and are relatively prime.

In contrast, group selectionists find examples of altruism among non-genetic relatives and explain this through selection acting on the group, whereby it becomes selectively advantageous for groups if their members express altruistic behaviours to one another.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors.

EC 1.1 includes oxidoreductases that act on the CH-OH group of donors (alcohol oxidoreductases)

EC 1.3 includes oxidoreductases that act on the CH-CH group of donors (CH-CH oxidoreductases)

EC 1.4 includes oxidoreductases that act on the CH-NH group of donors (Amino acid oxidoreductases, Monoamine oxidase)
