The coefficient of variation only indicates the extent of total variability present for a character and does not split the variability into heritable and nonheritable portions as reported [21, 22].
"Nonheritable influences, particularly microbes, seem to play a huge role in driving immune variation," said Davis.
Stable and plastic epigenetic regulation might help researchers to understand the molecular basis of heritable and nonheritable factors, but we still need a considerable effort to get as much evidence as possible on the evolutionary bases of the epigenetic phenomenon.
There are other nonheritable congenital bony conditions that arise from the sinuses or affect them as a result of their anatomic location.
In the nonheritable form, both allelic mutations are somatic, limiting disease to one eye with delayed presentation compared to those with the heritable form [3].
Moreover, renal dysplasia is most frequently a nonheritable condition (with very few exceptions).
These cases probably represent rare events and are likely to be of no great consequence to the survival of any species if they are the result of random nonheritable genetic defects that occur during limb bud development.
Selections are made, in part, on the basis of nonheritable characteristics and so reveal prevailing social hierarchies and the operation of what we call populist market eugenics industry reflect not just the desires of consumers to have offspring who physically resemble them, but to have offspring who will be at the top of prevailing social hierarchies.
The total genetic variance among inbred individuals ([F.sub.IS] = 1) within subpopulations can be decomposed into heritable [[C.sub.GAW(1)]] and nonheritable components [[C.sub.GDW(1)] by the relation [V.sub.W(1)] = [C.sub.GAW(1)] + [C.sub.GDW(1)], analogously to the decomposition of total genetic variance among noninbred individuals ([F.sub.IS] = 0) within subpopulations into [V.sub.W(0)] = [V.sub.AW(0)] + [V.sub.DW(0)]([V.sub.DW(0)] is the variance of dominance deviations of noninbred individuals within subpopulations).
Advantages of molecular markers often cited include (1) the large number of independent markers available for analysis, (2) simple genetic control, (3) low levels of nonheritable variation, (4) apparent selective neutrality, and (5) the ability to distinguish between maternal and paternal parents (e.g., Palmer et al.
Variation in phenotypes of offspring due to effects of the maternal parent ([V.sub.M]) can be partitioned as follows: (1) into an additive, heritable component attributable to segregation of nuclear genes expressed in maternal individuals and influencing phenotypes of their progeny ([V.sub.Am]); (2) a component due to organelle genes, which are often maternally inherited; and (3) a nonheritable component, including effects due to maternal environment and to gene interactions expressed in the maternal parent (which we here subsume in [V.sub.Em]) in a manner analogous to the partitioning of direct effects.
The short-term effect often involves a rapid response to varying environmental factors and is nonheritable in nature.
Unlike conventional antibiotic resistance, which is typically caused by transferable genetic alterations that confer protection against antibiotics, tolerance implies a transient, nonheritable phenotype.
This form of retinoblastoma is unilateral and has been thought to be nonheritable. Our case exhibited a germline mutation that has been previously reported in heritable retinoblastoma, (6) although it is unclear whether that case was an isolated unilateral tumor or a multifocal and bilateral tumor.
White clover has a remarkable phenotypic plasticity which results in a nonheritable change in plant morphology in response to environment, season, and management or harvest (Brock et al., 1988; Solangaarachchi and Harper, 1989).
