The genetic variation of organisms has three sources they are mutation, gene flow and sexual reproduction.
Explanation:
Genetic variation are caused by mutation , random mating, random fertilization and recombination between homologous chromosomes during meiosis.
It is a variation in alleles and genes, among the populations. There is a genetic variation within the family of closely- related individuals. If it is a neighborhood there are many families and there is also genetic variation among that group.
An exact genetic copy of the parent organism is produced in asexual reproduction. It only introduces the genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.
Answer:
Predation.
Explanation:
Predation is a form of behavior organisms exhibit to survive.
Predation is the process whereby an organism capture it's prey and feed on it to survive. It is attacking an organism and feeding on it. The predator kills, and eat it's prey.
Spider capturing an insect is predation.
Answer: Your answer would be A
Explanation:one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
This is because of natural selection; since polar bears live in a rough environment, natural selection gives them more fur, more muscle, and can go longer without food
Answer:
A. wild life survey
Explanation:
That's was the only answer that involved observing the wild life while the manufacturing plant is operating.
