The Virus World, apparently, remained continuous in time, in terms of uninterrupted inheritance of substantial sets of virus-specific genes, since its emergence from the primordial gene pool at the precellular stage of evolution to this day.
> -wrap-foot> Three of the four lowest-scoring concepts deal with complex traits (continuous variation, polygenic inheritance, and multifactorial causation [concepts 6, 7, and 11, respectively, in Table 1]).
The departure from Mendelian (simple) inheritance to more continuous (complex) variation by Nilson-Ehle which provided a genetic framework to interpret Galton's classic work on the distribution of human height and other quantitative traits (notably by Fisher) is not mentioned.
A qualitative trait of "hypertension" could be subject to classic Mendelian laws of inheritance whereas a continuous "blood pressure" trait would constitute a non-Mendelian complex trait [6].
For example in complex animal systems, color polymorphisms tend to have unknown inheritance mechanisms, exhibit continuous or intermediate variation, result from assortative mating under natural conditions, and/or be sex-linked [ 3] as seen in the African cichlid fishes [ 7].
Herein, we have proposed to identify the mode of inheritance in a continuous scale using the degree of dominance h, which is based on the ratio of the odds ratio of the co-dominant contrast divided by the absolute value of the odds ratio of the additive contrast.
The RIL population distributions were continuous for all traits, suggesting quantitative inheritance in all cases and both in drought stress and nonstress environments.
Two concepts (continuous variation of complex traits and polygenic inheritance) were virtually absent from state standards.
In this paper, we propose an index (h) that measures the degree of dominance and allows inferring the mode of inheritance in GAS in a continuous scale.
The observed continuous distribution of GLS resistance indicates a quantitative nature of inheritance.
