Variation arise in any population by mutation
, random mating between organisms
, random fertilization
, and crossing over between chromatids of homologous chromosomes during meiosis.
<u>Explanation:</u>
Genetic variation or Inheritable variation is a general estimation that identifies the existing genetic differences over the population. These differences take place in the DNA or Genes and each variation is known as an allele.
Thus Genetic variation is also defined as the variation in alleles of DNA or genes that takes place among and within the population. Each individual is adopted to its nature and environment.
The Genetic Variation is achieved by mutation, mating and fertilizing between random organisms and cross over of chromatids during meiosis(cell division).

Answer: Likewise in pteridophytes, species also produces haploid spores through haploid stage. In diploid stage the two spores fuse together to form a prothallus which is a diploid stage. Hence, the similarity in the reproductive cycle of fungus and a pteridophyte is that both organisms produce haploid spores and exhibit diploid and haploid stages.
Explanation:
Cancer cells are created by mitosis. Mitosis is cell division. I don’t understand your question
<span>Chicks hatching from eggs is an innate behavior. Innate
behavioral adaptations are the result of millions of years of evolution. This
type of behavior is already "hard-wired" in the nervous system of
organisms and is usually inflexible. This is where a certain given stimulus triggers
the exact same response over particular organisms through time. The same adaptation
goes for other species that are naturally inclined to walk hours after their
birth, like giraffes and elephants do. It is in a way nature's natural
adaptation for species to survive through the course of time.</span>
