Some of the earliest examples of parent-offspring conflict were seen in bird broods and especially in raptor species. While parent birds often lay two eggs and attempt to raise two or more young, the strongest fledgling takes a greater share of the food brought by parents and will often kill the weaker sibling ().
The Westermarck effect has gained some empirical support. [2] Proponents point to evidence from the Israeli kibbutz system, from the Chinese Shim-pua marriage customs, and from closely related families.
Owners have been known to encourage rivalries as they tend to improve game attendance and television ratings for rivalry matches. Clubs can reduce fan aggression surrounding rivalry games by acknowledging rather than downplaying the conflict [2] because the rivalry is an integral part of fan identity. [3]

As the figure shows, each time that the mouse with the desired trait (in this case the lack of a gene (i.e. a knockout), indicated by the presence of a positive selectable marker) is crossed with a mouse of a constant genetic background, the average percentage of the genetic material of the offspring that is derived from that constant ...
Σfxy = 1.g 1 + 0.g 2 + 0.g 3 + 0.g 4 = g 1. Σfx = g 1 + g 2 = p A. Σfy = g 1 + g 2 = p B. The covariance between x and y values is Σfxy - Σfx Σfy = g 1 - p A p B. which is equivalent to the LD coefficient, D, as defined above. It is usually convenient to calculate the correlation rather than the covariance, normalising by the variances:
Factors that influence female intrasexual competition include the genetic quality of available mates, hormone levels, and interpersonal dynamics. There are two modes of sexual selection: intersexual selection and intrasexual selection. Intersexual selection includes the display of desirable sexual characteristics to attract a potential mate ...
Genetic incompatibility describes the process by which mating yields offspring that are nonviable, prone to disease, or genetically defective in some way. In nature, animals can ill afford to devote costly resources for little or no reward, ergo, mating strategies have evolved to allow females to choose or otherwise determine mates which are more likely to result in viable offspring.
