An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Autosomal genetic studies have confirmed that Basques share close genetic ties to other Europeans, especially with Spaniards, who have a common genetic identity of over 70 % with Basques, a homogeneity amongst both their Spanish and French populations, according to high-density SNP genotyping study done in May 2010, and a genomic ...
Genetic variability is either the presence of, or the generation of, genetic differences. It is defined as "the formation of individuals differing in genotype , or the presence of genotypically different individuals, in contrast to environmentally induced differences which, as a rule, cause only temporary, nonheritable changes of the phenotype ."
genetic variation The genetic differences both within and between populations, species, or other groups of organisms. It is often visualized as the variety of different alleles in the gene pools of different populations. genetic variability. Sometimes used interchangeably with genetic variation.
The Basques (/ b ɑː s k s / BAHSKS or / b æ s k s / BASKS; Basque: euskaldunak [eus̺kaldunak]; Spanish: vascos; French: basques ⓘ) are a Southwestern European ethnic group, [6] [7] [8] characterised by the Basque language, a common culture and shared genetic ancestry to the ancient Vascones and Aquitanians.
If for genetic modification genes of the species or of a crossable plant are used under control of their native promoter, then they are called cisgenic plants. Sometimes genetic modification can produce a plant with the desired trait or traits faster than classical breeding because the majority of the plant's genome is not altered.
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...
A graphical representation of the typical human karyotype.. Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It ranges widely, from the number of species to differences within species, and can be correlated to the span of survival for a species. [1]
