sexual reproduction is the major cause of variations within a specie
The cause of variation are firstly genetic itself, 2nd) crossing over, 3rdly) indipendent assortment
Sexual Reproduction Genetic mutation
The small numbers of surviving tigers are a cause of worry from the point of view of genetics because less variation is present in the genetic characteristics of tigers. If they are decreasing in number due to change in natural condition, they may extinct very soon gene pool of tiger will be lost from existing environment it also indicates that tiger variants are not adopted to the existing environment.
Abrupt changes in the frequency cause mostly by abrupt variation in load is frequency scintillation.
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
No, Autism doesn't make you lose your hair - how could it? Autism is a neurological variation, it's no more likely to cause hair loss than any other neurological variation.
sexual reproduction is the major cause of variations within a specie
Reproduction produces variation in population gene pools. Every time organisms reproduce, be this sexually or asexually, the genome of the offspring is slightly offset compared to that of its parent(s). Additional factors in this may be mutagenic influences in the environment, such as radiation.

It causes pulsation or shudder on the brake pedals.
Answer 1If you have group of a species with dark skin and another group with light skin in an environment with much direct sunlight, the dark skinned gene group will be selected as the dark skin (with more melanin) is protective in that sunlit environment. If the environment is northern, the lighter skin gene will become more common. This variation will be a help in natural selection.Answer 2Genetic variation, or reproductive variation, are the mechanisms that cause one sibling to be slightly different from another. It is this difference that allows natural selection to work, for there may be various reasons, to do with these differences, why one sibling is more successful in producing offspring than the other.
