Radiation induced developmental instability in Arabidopsis thaliana
Theoretical and Applied Genetics, 1983In a study on the nature of induced genetic variations in quantitative characters using the selfpollinated plant Arabidopsis thaliana, it was observed that not only quantitative performance but also intraline variability, or developmental instability, was affected by induced mutations.

Inheritance of Developmental Instability
2003Abstract Fluctuating asymmetries (FAs) are nondirectional departures from perfect symmetry. FA is often used as a measure of developmental instability (DI), a hypothetical construct that we use to refer to the idea, that in some cases, variance in morphological traits may be maladaptive. Asymmetry is a logical way to approach this issue,

Amplified developmental instability in Down's syndrome
Annals of Human Genetics, 1975It is suggested that the extra chromosome in Down's syndrome (DS) results in a generalized decrease in canalization of development. Three palatal dimensions - height, width and anteroposterior length - were measured in moreal twins and in DS subjects.

Nonlinear Dynamics and Developmental Instability
2003Abstract The classical theory of developmental instability is a theory of linear dynamics. According to this view, developmental instability results from the additive accumulation of small developmental errors. Because these errors were thought to be additive and linear, fluctuating asymmetry, which is the most common measure of ...

Evolutionary Ecology and Developmental Instability
Annual Review of Entomology, 1995The past decade has seen a resurgence of interest in developmental instability, reflected in fluctuating asymmetry, as a concept in evolutionary ecology. Many investigations interpret fluctuating asymmetry in populations or subsets of populations as reflecting the existence of, or at least the potential for, natural or sexual selection.

Outbreeding causes developmental instability in Drosophila subobscura
Evolutionary Ecology, 2010A possible effect of interpopulation hybridization is either outbreeding depression, as a consequence of breakdown of coadapted gene complexes which can increase developmental instability (DI) of the traits, or increased heterozygosity, which can reduce DI.

Causes of developmental instability. Environmental factors
1997Abstract A large number of environmental factors can result in a reduction of developmental stability and increased levels of fluctuating asymmetry in bilateral traits. The list of factors is almost endless and the review given here is not exhaustive but merely a representation of the kinds of factors that researchers have thought ...

Journal of Theoretical Biology, 2005
The developmental mechanisms behind developmental instability (DI) are only poorly understood. Nevertheless, fluctuating asymmetry (FA) is often used a surrogate for DI. Based on statistical arguments it is often assumed that individual levels of FA are only weakly associated with the underlying DI.

Causes of developmental instability. Genetic factors
1997Abstract The factors that cause fluctuating asymmetry can be either genetic or environmental in origin. As fluctuating asymmetry represents the ability of an individual to resist genetic and environmental factors during growth and development, then it could be viewed as a general health certificate of an individual. In this chapter we

Developmental Instability as a Bet-Hedging Strategy
Oikos, 1997In temporally varying environments selection will often act, at the expense of expected fitness in any given generation, so as to maximize geometric mean fitness across a number of generations (Gillespie 1977). Such "bet hedging" (Slatkin 1974) may occur in two ways (Seger and Brockmann 1987).
