In this context heterogeneity may be induced by a combination of host behaviour, host genetics and past or current experience of infection.
The genetic analysis of these age-dependent phenotypes, termed growth trajectories, has long been of interest to students in different disciplines of biology and genetics.
In the realm of hereditary genetics there are more precise examples of threshold phenomena as well.
Genetics of monoamine metabolites in baboons : overlapping sets of genes influence levels of 5-hydroxyindolacetic acid, 3-hydroxy-4-methoxyphenylglycol, and homovanillic acid.
Chapter 2 focuses on the impact of genetics on evolutionary biology and recent research that ties issues in evolution to developmental biology.
As relativity was destroying the notion of determinacy in physical studies, genetics was bolstering it within biology.
The topics covered in both volumes include contributions on psychiatric genetics, autism, conduct disorders, social psychiatry and the importance of longitudinal and prospective studies.
These concepts lead to further complexity in understanding the genetics of complex diseases, such as the primary psychiatric conditions.
