Variations occurs in species due to the process of "Crossing over"
It has adaptations
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
what is this, your homework? yes and its hard.
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
Human species, as in the variation in height.
A variation in characteristics within populations of the same species is called intraspecific variation. This variation can occur due to genetic differences, environmental factors, and developmental processes, leading to diverse traits among individuals in the same species. Understanding intraspecific variation is crucial for studying evolution, ecology, and conservation.
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.

Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
The process of crossing over during meiosis increases genetic variation within a species by shuffling genetic material between homologous chromosomes. This genetic diversity enhances the ability of a species to adapt to changing environments and increases the likelihood of beneficial traits being passed on to offspring. Ultimately, this can improve the species' chances for survival and successful reproduction.
The word used to describe the differences within a species is "variation." Variation refers to the genetic, phenotypic, or behavioral differences among individuals of the same species, which can arise due to genetic mutations, environmental factors, or sexual reproduction. These variations are essential for the process of natural selection and evolution.
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
Of course, variation exists within individuals of the same species. This is because there are a small minority of genes which have multiple alleles in most species. In cases where a subset of the population is isolated from the rest of the population, a subspecies may develop which has particular unique characteristics but can still interbreed with the rest of the species.
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
