se·lec·tion

(sĕ-lek'shŭn),
The combined effect of the causes and consequences of genetic factors that determine the average number of progeny of a species that attain sexual maturity; phenotypes that are lethal early in life (for example, Tay-Sachs disease), that cause sterility (for example, Turner syndrome), or that produce sterile progeny are selected against. When selection is used of individual pedigrees, other factors, notably variance of the number of progeny and number that survive to maturity, are important considerations; in large populations, these factors even out and the mean only is of importance.
[L. se-ligo, to separate, select, fr. se, apart, + lego, to pick out]

selection

(sĭ-lĕk′shən)
n.
Biology A natural or artificial process that involves the survival and reproduction of some kinds of organisms instead of others (because they have traits that are better adapted to the environment or that are preferred by a breeder, for example) and results in changes in the traits of a population or species.

se·lec′tion·al (-shə-nəl) adj.

selection

Vox populi The chosing among a number of different options. See Adverse selection, Artificial selection, Group selection, Kin selection, Negative selection, Patient selection, Sex selection.

selection

the differential rate of reproduction of one phenotype in a population as compared to other phenotypes. Hence an organism that produces more offspring which survive to reproduce than another type is at a ‘selective advantage’. The environmental pressures causing selection can be either natural (e.g. competition for food) or artificial (e.g. insecticides, see DDT). See DIRECTIONAL SELECTION, NATURAL SELECTION, STABILIZING SELECTION.

Q. clonex symptoms in Selective Mutism Syndrome children My son is 6.5 years old, with selective mutism syndrome - in a months time he shall be entering first grade. We have, the past 2 years been with therapists specializing in this field. He has improved outside a closed system i.e. within the kindergarten (primarily) we even see some regression. We have been at major dilemmas with giving him medication but due to the critical time - we were recommended to take 0.125 mg of Clonex medication. we are a little worried and would like to understand the possible symptoms
