Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
sexual reproduction is the major cause of variations within a specie
All species have genetic variation. ;D
The revolution path of earth around sun & angle of tilting of earth at it's axes both are major cause of temperature variation at given point on earth.
Too much hunting or diseases.
The main source of genetic variation is a large population with a large gene pool.
Changes in the environment. (And these days mankind is a major changer.)
Loss of one species from a community has a large effect. This is because this can cause major changes in food webs and chains and can cause other organisms to die.
a measurable trait in which there is some evidence of the operation of a simple major cause, but in which the variation within the putative categories is such as to cause overlap and hence ambiguity in classification of any particular reading.
Continued hunting of this kind of animal Removal of their natural habitat (flora and fauna)
yes and no. when you huff anything its out of your system withing a few hours. ive done major research on this.
mutation and recombination
Darwin's three major contributions to evolutionary thought are; 1. There is genetic variation in all species 2. The variability is inherited - passed from parents to offspring 3. There are more offspring born than that survive to reproductive age
Recombination, or crossing over, is the process by which homologous chromosomes exchange genetic material during meiosis. This creates gametes with many different combinations of alleles, and is a major source of genetic variation in sexually reproducing species.
Depends on if you want Major or Minor species 3 Major species: * Arabica * Robusta * Liberica * There are actually only two, Arabica and Robusta. Liberica is a sub species of Arabica
what is the major cause of carcinoma cancer
A species name may tell the scientific name of the species and a major trait of the species
The Major cause of death for Jauguars are the hunters.
the major cause of halitosis is bad smelling breath
Mutation produces genetic variation very rapidly in prokaryotes (bacteria) and viruses due to their short generation spans.
