The measure of variation which exists in the genetic makeup of any particular individual within a population is genetic variation. There are several key features and advantages associated with the genetic variation as it is an important factor causing evolution allowing natural selection thus leading to increase or decrease the frequency of alleles in a population.
The other factors causing genetic variation include random mating, mutation, random fertilization and recombination during meiosis between the homologous chromosomes.
The main advantage of genetic variation is it enables the individuals to adapt to environment as well as maintaining the survival of the population.
Based on the information on genetic variation we can conclude whether there is increase or decrease in the genetic variation of the population in the gene pool.
• A zebra migrates to join a different herd of zebras- Increase
• Competition for sunlight leads to taller trees- Decrease
• The DNA of a snake changes to make its venom stronger- Increase
• A grass-fire randomly sweeps through a population of buffalo and kills most of the animals- Decrease
"Not all members of a species are the same. Every species exhibits variations in different traits like eye color, that are passed from parent to offspring."
This statement is paraphrased from the Darwins's theory. Darwin's theory suggested that there are variations among individuals in a population and that these variations will help individuals to survive. Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes.
6 turns<span>Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle.</span>
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize
