An offspring that is the result of mating between two genetically different kinds of parents--the opposite of purebred.
Industry:Anthropology
An inherited trait that is determined by genes at two or more loci. Simple Mendelian rules of dominance do not apply to the complex interaction of these genes. As a result, phenotypes may appear as apparent blends or intermediate expressions. Human skin and hair color are polygenic traits. Many polygenic traits are also influenced by environmental factors.
Industry:Anthropology
An inherited metabolic disorder in which there are abnormally high blood sugar levels. In advanced stages, this often results in blindness from cataracts, nerve damage, gangrene in the feet and legs leading to amputation, heart disease, and kidney failure. Type 1 diabetes melitis (juvenile onset diabetes) is due to decreased production of insulin by the pancreas. Type 2 diabetes melitis is due to increased resistance of cells in the body to insulin. The gene or genes for diabetes are incompletely penetrant.
Industry:Anthropology
An inheritance pattern in which a gene will have a different effect depending on the gender of the parent from whom it is inherited. Genome imprinting is also known as genetic imprinting.
Industry:Anthropology
An individual who is heterozygous for a trait that only shows up in the phenotype of those who are homozygous recessive. Carriers often do not show any signs of the trait but can pass it on to their offspring. This is the case with hemophilia.
Industry:Anthropology
An individual who is genetically two people. Fully chimeric individuals are usually the product of two fertilized ova fusing into a single embryo shortly after conception.
Industry:Anthropology
An individual who has one or more testes and ovaries and whose external genitalia are not clearly male or female. This condition can occur in chimeras who have inherited both a male and a female set of sex chromosomes. True hermaphrodites have one testes and one ovary. Male pseudohermaphrodites, or "merms," have testes but no ovaries and display some female genitalia tissue. Female pseudohermaphrodites, or "ferms," have ovaries but no testes and display some male genitalia tissue.
Industry:Anthropology
An animal that travels through the trees by swinging under branches with a hand over hand motion. The smaller apes and some New World monkeys brachiate.
Industry:Anthropology
An incorrect 19th century theory about the inheritance of characteristics. It proposed that inherited traits blend from generation to generation. Through his plant cross-breeding experiments, Gregor Mendel proved that this was wrong.
Industry:Anthropology
An inadequacy or an excess of some key element(s) in the diet, such as proteins, fats, or specific minerals and vitamins. See undernourishment and overnourishment.
