Monogamy

Each individual mates exclusively with one partner over at least a single breeding cycle and sometimes for longer.

Monogamy occurs in fish, amphibians, reptiles, and mammals, but it is only commonly observed in birds, some rodents, and a few primate species.

During anaphase, when cyclin B-CDK1 activity is extinguished but Aurora and Polo kinases are still active, Aurora B phosphorylates MKLP1 and displaces the 14-3-3, allowing compact the spindle midzone.

A recessive allele (a) that causes a genetic disease has a frequency (q) of 0.01. If the population mates randomly (F = 0), the frequency of individuals affected by the disease (aa) will be q = 0.01 = 0.0001.

However, if F = 0.25 expected frequency of the aa is .0026.
