overlapping sexual populations

In a two-page paper, identify a known healthcare disparity in American Indians.

 Analyze how the select population’s culture, values and traditional healthcare beliefs may impact health promotion efforts.

May lead to small actual gamodemes which exchange gametes reasonably uniformly. Within themselves but are virtually separate from their neighboring gamodemes.

However, there may be low frequencies of exchange with these neighbors.

This may be view as the breaking up of a large sexual population (panmictic) into smaller overlapping sexual populations. This failure of panmixia leads to two important changes in overall population structure. The component gamodemes vary (through gamete sampling) in their allele frequencies when compared with each other and with.

The theoretical panmictic original (this is known as dispersion, and its details can be estimate using expansion of an appropriate binomial equation). And (2) the level of homozygosity rises in the entire collection of gamodemes. The overall rise in homozygosity is quantified by the inbreeding coefficient (f or φ). Note that all homozygotes are increase in frequency – both the deleterious and the desire. The mean phenotype of the gamodemes collection is lower than that of the panmictic original . Which is know as inbreeding depression.

It is most important to note, however, that some dispersion lines will be superior to the panmictic original.

While some will be about the same, and some will be inferior. The probabilities of each can be estimate from those binomial equations. In plant and animal breeding. Procedures have been develop which deliberately utilize the effects of dispersion (such as line breeding, pure-line breeding, backcrossing).

It can be shown that dispersion-assist selection leads to the greatest genetic advance (ΔG=change in the phenotypic mean). And is much more powerful than selection acting without attendant dispersion. This is so for both allogamous (random fertilization) and autogamous (self-fertilization) gamodemes
