Accordingly, the value of fitness ...

Accordingly, the value of fitness, obtained at the expense of the whole resource X, will be equal to KX. As a resource is meant anything that may increase the fitness, the conversion factor K fitness resource can be viewed as the coefficient of the effectiveness of their own genes. If, for example, chronic diseases such coefficient K could drop significantly. As is known, the basic components of fitness - the viability and reproductive performance (fertility). To ensure its vitality to the patient need more resources than the healthy, as part of the resource will go to fight the disease. The difference in volume (quantity) of resources allocated to providing reproductive patients and healthy subjects can be considerable (for reproductive means not only the birth of a full-fledged offspring, but growing, protecting it). This is a significant decrease in the coefficient K may be due to age . (This is not only the fact that with age, the food resource is processed less efficiently, but primarily to the fact that from a certain age period, the probability of a full grown child, to protect it falls.) That would mean a lowering of the coefficient K in more than twice, for example in 2,5 times, compared with the same index of my brother? This would mean that any victim of any X resources transferred to his brother (r = 0,5), would be for him more than 2 times more valuable, ie, KdonX / KretsX (or B / C) will always be smaller than r. In accordance with the theory of kin-selection, this will mean that every victim of the donor, the transfer of any share of a recipient, if Krets r> Kdon will selectively benefit the most donoru.Takaya sacrifice will not be selectively advantageous for an abundance of resources, when possible save and donor resources and the resource of the recipient. But for lack of resources, individual donors, even those with some level of fertility will be selectively advantageous to provide individual, having a K r> Kdonora resource fully to the level of "maximum load", and only the remaining resources to take sebe.Esli such individuals with an exponent K r> Kdon will be several - is selectively useful to provide a resource of them all. If we consider identical genes, as equal, equivalent to its own, then lowering the coefficient of K individuals in more than two times, will mean a more efficient distributor of any gene of this individual is already not this individual, and her cousin with a coefficient of genetic relatedness = 0 , 5 (in which the coefficient K is not dropped). By lowering its own coefficient K by more than 2 times the individual loses the status of the main distributor of their own genes. Situation when the individual is the primary distributor of their own genes differs significantly from the situation in which the individual is not. We denote this situation number 1 and number 2. But can occur and the situation number 3. Page 3 If the individual has given the entire resource is the main distributor of their own genes, leaving himself only on the livelihood of his own body, but it's given up life still is not enough to "fully loaded", ie
