Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms.

A rearrangement of genetic material between regions of chromosome 9 and 22 is common in patients with a form of leukaemia, as it was discovered this translocation created a fusion of two genes that resulted in increased cell division. It is clear the influence that genetic variation can have on the health of an individual is complicated.

Types of Biodiversity: (a) Genetic diversity: It is the variation of genes within the species. This results distinct population of one, even same species. It gives genetic variation within a population or varieties within one species. There are two reasons for differences between individual organisms.

The two main sources of genetic variation are mutations and re combinations of genes as a result of sexual reproduction. A mutation is a permanent change in the DNA within a gene. Some mutations, which affect all cells in an organism, are inherite...

genetic variation: variation in alleles of genes that occurs both within and among populations; Genetic Variation. Genetic variation is a measure of the genetic differences that exist within a population. The genetic variation of an entire species is often called genetic diversity. Genetic variations are the differences in DNA segments or genes ...

Type 2 diabetes (T2D) is a complex disorder in which both genetic and environmental risk factors contribute to islet dysfunction and failure. Genome-wide association studies (GWAS) have linked single nucleotide polymorphisms (SNPs), most of which are noncoding, in >200 loci to islet dysfunction and T2D. Identification of the putative causal variants and their target genes and whether they lead ...

Sexual reproduction increases genetic variation in offspring, which in turn increases the genetic variability in species. You can see the effects of this genetic variability if you look at the children in a large family and note how each person is unique. Imagine this kind of variability expanded to include all the families you know […]

What is a genetic disease or disorder? Learn from a list of genetic diseases that are caused by abnormalities in an individual's genome. There are four main types of genetic inheritance, single, multifactorial, chromosome abnormalities, and mitochondrial inheritance. Genetic testing is available for some genetic diseases.
