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.
Cross breeding is the process of breeding with the intention to create offspring that share the traits of both parent lineages or to produce an animal with hybrid vigour (the improved or increased function of any biological quality in a hybrid offspring). [1]
