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.
Crossing over between the loci separates linked genes. Crossing Over Animation from Tokyo Medical University Genetics Study Group. Crossing over is more likely to separate alleles at two gene loci if they are widely spaced on the same chromosome than if they are located close to each other (closely linked).
