phenotypic variation उदाहरण वाक्य

:: After the rise of the New Left amongst academia, a modified population genetics reflected a new understanding of the sources of phenotypic variation.
A few children with a milder, chronic form of this disorder have been reported, and there can be considerable phenotypic variation, even within families.
Since the cause of FAD has not been genetically pinpointed, the only way to diagnose FAD is through the examination of phenotypic variations in the aorta.
The condition has however occurred in surprising clinical situations, and because of phenotypic variations among individuals, it has been associated with unexpected drugs, including mirtazapine.
Phenotypic variations observed among patients probably result from differences in their genetic background and may depend on which particular amino acid in the NCCT protein has been mutated.

High genetic diversity within a population can lead to high phenotypic variation, which can subsequently enable some variants to better survive and reproduce given a sudden environmental change.
Broad-sense heritability, H 2 = V G / V P, Involves the proportion of phenotypic variation due to the effects of dominance and epistasis variance.
On the other hand, heritability might also increase if the environmental variation decreases, causing individuals to show less phenotypic variation, like showing more similar levels of intelligence.
The biometric ( or statistical ) conception has its origins in research programs that seek to measure the relative proportions of genetic and environmental contributions to phenotypic variation within populations.
Backcross progeny will have less phenotypic variation and comprise animals that are either heterozygous for each gene variant or homozygous for the variant found in the original F1 backcross parent.
