Related to lethal mutation: neutral mutation, Conditional lethal mutation

MUTATION, French law. This term is synonymous with change, and is particularly applied to designate the change which takes place in the property of a thing in its transmission from one person to another; permutation therefore happens when, the owner of the thing sells, exchanges or gives it. It is nearly synonymous with transfer. (q.v.) Merl. Repert. h.t.

If mutations are only mildly deleterious, it has been shown that they are much more difficult to purge than lethal mutations, and substantial inbreeding depression may be maintained even in selfing populations (Lande and Schemske 1985; Charlesworth et al.
If these data on chlorophyll deficiencies are representative of lethals in general, they indicate that genomic lethal mutation rates may be more than an order of magnitude higher in trees than in annual plants (Klekowski and Godfrey 1989).
Small, isolated founder populations such as these are expected to carry fewer harmful recessive mutations than the general population, because lethal mutations are more effectively selected against by natural selection in small populations.
Expression of delayed toxicity and lethal mutations in the progeny of human cells surviving exposure to radiation and other environmental mutagens.
London, July 29 ( ANI ): Two researchers have claimed that the bugs are now developing potentially lethal mutations in order to beat domestic cleaning agents that have been designed to kill them.
But both lethal mutations, most of which act early in embryonic development, and sterility mutations are hard to observe phenotypically.

Finally, it may explain why other types of adult stem cells are susceptible to accumulating potentially lethal mutations.
The background genome was modeled after the method of Kondrashov (1985), and simplified by considering only lethal mutations (Lande et al.
Estimates of mutational variances and covariances obtained from mutation accumulation against a balancer will be disproportionately influenced by the first class as, in this case, recessive mutations are virtually sheltered from natural selection (lines carrying lethal mutations were usually excluded from analyses).
