The first adoption study on schizophrenia published in 1966 by Leonard Heston demonstrated that the biological children of parents with schizophrenia were just as likely to develop schizophrenia whether they were reared by their parents or adopted [5] and was essential in establishing schizophrenia as being largely genetic instead of being a result of child rearing methods.
Adoption may threaten triad members' sense of identity. Triad members often express feelings related to confused identity and identity crises because of differences between the triad relationships. Adoption, for some, precludes a complete or integrated sense of self. Triad members may experience themselves as incomplete, deficient, or unfinished.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
The question starts by discussing the high school’s diversity and noting that so-called African American traits have infiltrated students of other races.
In these examples, the source of selection on a trait coevolves with the trait itself, therefore causation is reciprocal and developmental processes potentially become relevant to evolutionary accounts. For instance, a peacock’s tail evolves through mating preferences in peahens, and those preferences coevolve with the male trait.
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
The social insects provide good examples of organisms with what appear to be kin selected traits. The workers of some species are sterile, a trait that would not occur if individual selection was the only process at work. The relatedness coefficient r is abnormally high between the worker sisters in a colony of Hymenoptera due to haplodiploidy.
Monkeyluv: And Other Essays on Our Lives as Animals is a 2005 non-fiction book by Robert Sapolsky. It collects eighteen essays on biological topics previously published by Sapolsky in various magazines, with additional notes and three section introductions. It has been reviewed in The New York Times, [2] Kirkus Reviews, [1] and New Scientist. [3]
