Eugenics The science of improving a human
population by
controlled breeding to increase the
occurrence of
desirable heritable characteristics.
Developed
largely by Francis Galton as a method of
improving
the human race, it fell into disfavor only
after the
perversion of its doctrines by the Nazis.
Genomic imprinting Phenomenon by which certain genes are
expressed in a parent-of-origin-specific
manner. If
the allele inherited from the father is
imprinted, it is
thereby silenced, and only the allele from
the
mother is expressed. If the allele from the
mother is
imprinted, then only the allele from the
father is
expressed.
,Functionalism Suggests that cognitive processes were
governed
by the function of the mind; focused on the
utility
of consciousness and considers mental life
and
behaviour in terms of active adaptation to
the
person's environment.
Structuralism Theory of consciousness developed by
Wilhelm
Wundt and his mentee Edward Bradford
Titchener
which attempted to understand the mind
as the
sum of varying underlying parts. Proposes
that
consciousness is best understood through
the
systematic study of the anatomy of the
brain
, Developmental noise A concept within developmental biology in
which
phenotype varies between individuals even
though
both the genotypes and the environmental
factors
are the same for all of them; human
fingerprints
provide a well-known example; the
fingerprints
differ even between genetically identical
human
twins.
Gene-environment interaction Genes are not "set in stone; the
expression of
genes in an organism can be influenced by
the
environment, including the external world
in which
the organism is located or develops, as
well as the
organism's internal world, which includes
such
factors as its hormones and metabolism.
Polygenic Traits that are controlled by multiple genes
and/or
influenced by the environment, such as
height, skin
color, eye color, weight
