Genetic variation is important to the processes ofnatural selectionandbiological evolution. The genetic variations that arise in a population happen by chance, but the process of natural selection does not.Natural selectionis the result of the interactions between genetic variations in a population and ...
Genetic diversity is defined as the total amount or the number of genetic variations, such as the diversity of genes (alleles) within a species or a population. Genetic variability is different from genetic diversity. Genetic variability measures how much the trait or the genotype will tend to ...
Ingenetics, variation refers to an individual that possesses characteristics different from the others of the same kind. Genetic variation usually arises as a mutation in a gene that encodes a protein or an RNA. Variations may be reflected in the phenotype of the individual, e.g. a difference ...
Successful variations accumulate over the generations as the organisms are exposed to population pressure."Natural Selection acts exclusively by the preservation and accumulation of variations which are beneficial under the conditions to which each creature is exposed. The ultimate result is that each crea...
A gene refers to the place on a chromosome that influences a specific trait, while alleles are variations of the genetic information that can occupy this space. For every one gene, there are two alleles, one from each parent. Allele frequency is the frequency in which an allele is present ...
Variations on Dominance Video duration: 4m 11 2 Problem Which of the following is NOT a type of dominance? A Complete dominance B Incomplete dominance C Codominance D Leaky dominance Ask a question 0 Comments Show Answer 3 Problem Which of the following parents could produce offspring with an ...
Genes are specific sequences of DNA that code for traits. Genes, like the ones that code for hair and eye color, manifest in several forms. This is due to alleles. Alleles are alternate versions of a gene that lead to variations in appearance. The genotype of an organism describes the ...
Individual variations in the pharmacological or toxicological responses to the same drug dose may be caused by a variety of factors such as body mass, age, sex, kidney and liver function, drug-drug (food-drug) interactions, and genetic variability [1]. Detailed knowledge of the metabolism of ...
Meiosis is essential as it is one of the major sources of genetic variations by way of genetic recombinations and chromosomal assortment. Cellular organization In multicellular eukaryotes, the zygote divides by a series of mitoses to give rise to stem cells that can develop and differentiate later...
Genetic Variation Share the same genetic information Can have different alleles and variations due to recombination and independent assortment Role in Genetic Inheritance Essential for the accurate transmission of genetic information to daughter cells Essential for genetic diversity and the reshuffling of gene...
