gray wolves variation trait
VARIATION
homozygous organisms
No.
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
Basic source of variation in all organisms is mutation .
Variation is important among organisms for us to indicate which is which :))
gray wolves variation trait
The two types of variation shown by living organisms are genetic variation, which is differences in DNA sequences among individuals, and phenotypic variation, which refers to observable traits or characteristics that vary among individuals.
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
VARIATION
Human recombination is a significant source of genetic variation.
homozygous organisms
Variations arise due to recombinations(gene rearrangements) ,mutations etc.The former is the principal source of variation in sexually reproducing organisms and the latter is the source of variation in asexual organisms.According to Darwin variation arises due to chance since all the above mentioned process occur in nature spontanuously all organisms show variation
Phenotype
No.
