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.
(For example, one phenotype of a pea plant is having purple flowers.) A dihybrid cross is a cross between two individuals that are both heterozygous for two different genes. A hybrid is just the offspring produced when two genetically different parents are crossed.
