Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
Homosexual behaviour is demonstrated by 120 known species of birds. [40] While an uptick in research on bird homosexuality – and animal homosexuality in general – has been coming out in recent years, it is common for some authors to labour in articulating the view any root cause or function of bird homosexuality is poorly understood.
These animals have been observed practicing homosexual courtship, sexual behavior, affection, pair bonding, or parenting. Bruce Bagemihl writes that the presence of same-sex sexual behavior was not officially observed on a large scale until the 1990s due to possible observer bias caused by social attitudes towards LGBT people, which made ...
[1] [2] Some animal sexual behaviour involves competition, sometimes fighting, between multiple males. Females often select males for mating only if they appear strong and able to protect themselves. The male that wins a fight may also have the chance to mate with a larger number of females and will therefore pass on his genes to their ...
[58] [64] This method can be used to increase a particular animal's contribution to the population. [58] While linebreeding is less likely to cause problems in the first generation than does inbreeding, over time, linebreeding can reduce the genetic diversity of a population and cause problems related to a too-small gene pool that may include ...
Its use in animal studies has been controversial for two main reasons: animal sexuality and motivating factors have been and remain poorly understood, and the term has strong cultural implications in western society that are irrelevant for species other than humans. [12] Thus homosexual behavior has been given a number of terms over the years.
Fixed. All occurrences of "hemophilia" have been changed to "haemophilia", except where "hemophilia" is the title of a reference. -bladebot 05:42, 26 September 2007 (UTC) I find it confusing that a Haemophila article links to Hemophilia A.
Symptomatic carriers of the gene, while not hemophiliacs themselves, can have symptoms of hemophilia including a lower than normal blood-clotting factor that can lead to heavy bleeding. [15] If Anastasia lived to have children of her own, it is genetically probable that they would have been afflicted by the disease.
