The order primate holds 300 or more species including monkeys, humans, gorillas, chimpanzees among others. The species included in this order share anatomic and functional characteristics such as:
- Hands and feet with 5 fingers and opposable thumbs, for grabbing, holding a grip for a better arboreal lifestyle. Even though in some species such as humans these opposable thumbs in feet don't longer exist.
- Plantigrade feet, which means that the toes and metatarsals are flat on the ground while walking.
- Collarbone or clavicle present.
- Nails instead of claws in the large majority of species.

It is the recessive trait that is visible in the F2 generation, but not the F1 generation of the Mendel Crosses.
In a recessive trait, the organism has two recessive allele or similar form of gene.
In the F1 generation all the off springs are heterogeneous with different allele but in the F2 generation the recessive allele comes from the alleles passed on by the parents (off springs of the F1 generation , which have recessive allele)
