Conservative paronia driven by homophobia. Irenaeus October 29, at 8:
Increased cardiovascular risks  The isolation of a small population for a period of time can lead to inbreeding within that population, resulting in increased genetic relatedness between breeding individuals.
Inbreeding depression can also occur in a large population if individuals tend to mate with their relatives, instead of mating randomly.
Many individuals in the first generation of inbreeding will never live to reproduce. This type of isolation may result in the formation of race or even speciationas the inbreeding first removes many deleterious genes, and permits the expression of genes that allow a population to adapt to an ecosystem.
As the adaptation becomes more pronounced, the new species or race radiates from its entrance into the new space, or dies out if it cannot adapt and, most importantly, reproduce.
This may mean that a species may not be able to adapt to changes in environmental conditions. Each individual will have similar immune systems, as immune systems are genetically based. When a species becomes endangeredthe population may fall below a minimum whereby the forced interbreeding between the remaining animals will result in extinction.
Natural breedings include inbreeding by necessity, and most animals only migrate when necessary. In many cases, the closest available mate is a mother, sister, grandmother, father, brother, or grandfather.
In all cases, the environment presents stresses to remove from the population those individuals who cannot survive because of illness. There was an assumption that wild populations do not inbreed; this is not what is observed in some cases in the wild.
However, in species such as horsesanimals in wild or feral conditions often drive off the young of both sexes, thought to be a mechanism by which the species instinctively avoids some of the genetic consequences of inbreeding. Historical analysis indicated that a population expansion from just two matrilineal lines was responsible for most of the individuals within the population.
Even so, the diversity within the lines allowed great variation in the gene pool that may help to protect the South American sea lion from extinction. When the dominant male is killed or driven off by one of these bachelors, a father may be replaced by his son.
There is no mechanism for preventing inbreeding or to ensure outcrossing. In the prides, most lionesses are related to one another. If there is more than one dominant male, the group of alpha males are usually related.
Two lines are then being "line bred". Also, in some populations, such as the Crater lions, it is known that a population bottleneck has occurred.
Researchers found far greater genetic heterozygosity than expected. However, killing another male's cubs, upon the takeover, allows the new selected gene complement of the incoming alpha male to prevail over the previous male.
There are genetic assays being scheduled for lions to determine their genetic diversity. The preliminary studies show results inconsistent with the outcrossing paradigm based on individual environments of the studied groups.View Notes - Public Speaking - Arranged marriages from SPC at University of South Florida.

Essay on Arrange Marriage vs. Love Marriage.
Marriage is an institution that is considered successful, if, it lasts lifelong. There are different customs and traditions that are followed in different societal set-ups. In Indian society, arranged marriages are known to exist since ages.
