Examples of genetic variation in animals include albinism, cheetahs with stripes, snakes that fly, animals that play dead, and animals that mimic leaves. These variations enable the animals to better adapt to conditions in their environments.

What are some variations in species?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
How can animals have variation?
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.
What is variation and example?
Variation is how much something differs from another. An example of variation is light blue to dark blue.
What are some examples of variation in traits?
Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene.
What are three variations examples?
Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
What are the 3 types of variation?
Genetic variation – the variation in genotypes (i.e. the genes) between species or within a species. Phenotypic variation – the variation in phenotypes other features apart from the genes) between species or within a species e.g. variation in height, mass, shape, colour, blood type.
What animal has the most variation?
The tiny water flea Daphnia has the most genes of any animal, some 31,000. Scientists have discovered that the animal with the most genes--about 31,000--is the near-microscopic freshwater crustacean Daphnia pulex, or water flea. By comparison, humans have about 23,000 genes.
What is variation class 10?
Variation is always the difference between an ideal and an actual situation. ... Between the individuals of the same species, there can be seen differences between the characteristics which is known as the Variation. During the reproduction, there are some variations that passed on from parents to offspring, via genes.
What are the 4 types of variation?
Examples of types of variation include direct, inverse, joint, and combined variation.
What variation do you see in plants?
Natural variation in plants refers to the genetic diversity of a single plant species in the wild. Natural variation is a valuable source of beneficial traits for plant breeding.
What are the two types of variation?
There are two forms of variation: continuous and discontinuous variation. Characteristics showing continuous variation vary in a general way, with a broad range, and many intermediate values between the extremes.
What is variation in one sentence?
the act of changing or altering something slightly but noticeably from the norm or standard. 1. The prices for food are subject to variation.
What is an environmental variation?
the ability of an organism to alter greatly its PHENOTYPE depending upon environmental conditions. The phenomenon is seen most clearly in plants, perhaps because they are fixed in the ground.
Which species have the least genetic variation?
In fact, according to the most recent study, published last week in the journal Current Biology, the San Nicholas Island fox (U.l. dickeyi) may have the lowest genetic variability of any other wild animal species on the planet.
What animal has the most DNA?
The Australian lungfish has the largest genome of any animal so far sequenced. Siegfried Schloissnig at the Research Institute of Molecular Pathology in Austria and his colleagues have found that the lungfish's genome is 43 billion base pairs long, which is around 14 times larger than the human genome.
Which animal is most genetically different to humans?
"This will allow us to look for the genetic basis of what makes modern humans different from both bonobos and chimpanzees." Ever since researchers sequenced the chimp genome in 2005, they have known that humans share about 99% of our DNA with chimpanzees, making them our closest living relatives.
