Manus (anatomy) The manus (Latin for hand) is the zoological term for the distal portion of the fore limb of an animal. In tetrapods, it is the part of the pentadactyl limb that includes the metacarpals and digits (phalanges). During evolution, it has taken many forms and served a variety of functions.
A cross between parents that differ in one trait is called monohybrid cross.
I found this helpful and interesting: during miosis you get gene cross-over meaning bits of the maternal or paternal chromosomes swap, which makes the offspring unique and not just half versions of its parent â ktamlyn May 12 '14 at 13:14.
