Inheritable genetic variation
The concept of heritable variation—the presence of innate differences between life forms that are passed from parents to offspring, especially within categories such as species—does not rely on modern ideas of genetics, which were unavailable to 18th- and 19th-century minds. Pre-Darwinian concepts of … Visa mer Genetic variation is the difference in DNA among individuals or the differences between populations. The multiple sources of genetic variation include mutation and genetic recombination. Mutations are the ultimate sources of … Visa mer Geographic variation means genetic differences in populations from different locations. This is caused by natural selection or genetic drift. Visa mer Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare, and most mutations are neutral or deleterious, but in some instances, the new alleles can be … Visa mer A variety of factors maintain genetic variation in populations. Potentially harmful recessive alleles can be hidden from selection in the heterozygous individuals in populations of diploid organisms (recessive alleles are only expressed in the … Visa mer Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either … Visa mer Genetic variation within a population is commonly measured as the percentage of polymorphic gene loci or the percentage of gene loci in heterozygous individuals. The results can be very useful in understanding the process of adaption to the environment of … Visa mer Genetic variation can be divided into different forms according to the size and type of genomic variation underpinning genetic change. … Visa mer WebbSeveral lines of evidence suggest that niacin-induced dermal flush may be a biomarker for schizophrenia (Ward et al., 1998; Puri et al., 2001; Liu et al., 2007). Up to 80% of schizophrenic patients show diminished niacin flush as compared with 20% of healthy individuals (Ward et al., 1998; Puri et al., 2001). As the niacin flush is highly inheritable …
