Environment and inheritance: opposing forces?
High risk of schizophrenia requires high genetic predisposition to develop schizophrenia, plus an environmental trigger. A schizophrenic family environment is commonly believed to represent this trigger. The hypothesis is presented here that, on the contrary, a high predisposition to schizophrenia in significant others protects against overt illness. The trigger may be the predominance around t...
متن کاملPrimary angle-closure glaucoma. Inheritance and environment.
The picture of primary angle-closure glaucoma accompanied by its shallow anterior chamber is so distinct that for many years it has evoked considerable curiosity concerning possible genetic determination. Family trees were published (Sedan and Sedan-Bauby, 1949; Waardenburg, I96I) and attempts were made to fit the inheritance into a genetic pattern-but without convincing success. Authors seemed...
متن کاملGenetic Variation and Inheritance of Early Growth Characteristics in Three Wild Pistachio Populations
Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...
متن کاملMitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملAnalysis of the inheritance, selection and evolution of growth trajectories.
We present methods for estimating the parameters of inheritance and selection that appear in a quantitative genetic model for the evolution growth trajectories and other "infinite-dimensional" traits that we recently introduced. Two methods for estimating the additive genetic covariance function are developed, a "full" model that fully fits the data and a "reduced" model that generates a smooth...
