The Muller's ratchet in evolutionary genetics refers to a procedure by which gathering of harmful mutations takes place in an irreversible way by the genomes of an asexual population. Muller suggested this process as one of the cause that why sexual reproduction can be considered over to asexual reproduction.
The main influence of Muller's ratchet is the gathering of somewhat deleterious mutations. Such gathering of mutation can at certain occasions result in eventual extinction.
This takes place if population size is finite, recombination is absent, slightly deleterious rates of mutations are high, almost no back mutations takes place, and purifying selection is very weak to eradicate all the novel deleterious mutations.

Endocrine gland - a group of cells that secretes substances into the blood or directly into an organ.
Differ from exocrine glands, endocrine glands have no ducts and secrete products (hormones) directly into blood.
Hormone - a substance produced by cells that helps specific groups of cells to perform specific functions. It is a product of endocrine gland which functions as chemical messengers to stimulate other cells.
Duct – a channel or tube that conveys a substance. It is part of the exocrine glands (such as salivary glands) which makes contact with surface .
