Afact that a biological system – individual and population – is different over space. it is the base of the genetic variability of different biological systems in space. genetic variation is based on the variation genes in a it occurs both within and among populations, supported by individual carriers of the variant genes. genetic variation is brought about by , which is a permanent change in of a gene.

Explanation:

Genetic variation is a fact that a biological system – individual and population – is different over space. It is the base of the Genetic variability of different biological systems in space. Genetic variation is based on the variation in alleles of genes in a gene pool. It occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about by random mutation, which is a permanent change in the chemical structure of a gene.

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
