Animals avoid inbreeding only rarely. [2] Inbreeding results in homozygosity which can increase the chances of offspring being affected by recessive traits. [3] In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population [4] [5] (called inbreeding depression), which is its ability to survive and ...
This process of integrating and organizing experience, called the emergent sense of self, continues until about two months. It serves as "the basis for the child's ability to learn and create," [citation needed] and is what Stern believes is the sense of self that is disrupted in the negative symptoms of schizophrenia and other psychotic disorders.
Neoteny in humans is the slowing or delaying of body development, compared to non-human primates, resulting in features such as a large head, a flat face, and relatively short arms. These neotenic changes may have been brought about by sexual selection in human evolution .
To find the coefficient of inbreeding of G, first locate a loop that leads from G to the common ancestor through one parent and back down to the other parent without going through the same individual twice. There are only two such loops in this chart, as there are only 2 common ancestors of C and F.
Darwin's wife, Emma, was his first cousin, and he was concerned about the impact of inbreeding on his ten children, three of whom died at age ten or younger; three others had childless long-term marriages. [16] [17] [18] Humans do not seek to completely minimize inbreeding, but rather to maintain an optimal amount of inbreeding vs. outbreeding.

The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy.
Often small for gestational age (SGA) at birth (birth weight less than 2.8 kg) Feeding problems: the baby is uninterested in feeding and takes only small amounts with difficulty; Hypoglycemia; Excessive sweating as a baby, especially at night, and a greyness or pallor of the skin. This may be a symptom of hypoglycemia
