Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.
Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.
Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of London's peppered moths.

Gametophyte
The cells from the male and female that combine to form a zygote are called gametes. The main job of the gametophyte is gamete production. Gametes are haploid reproductive cells. Gametes are produced in the sex organs on the haploid gametophyte by mitosis or cellular division without reduction of chromosomes sets. There are two sex organs; archegonium<span> which is found in the female sex organ producing egg cell and </span>antheridium<span> which is found in the male sex organ producing sperm cells.</span>
Answer and Explanation
The normal microbiota that harbouring an R plasmid will transmit its R plasmid to the normal microbiota because the normal microbiota does not have R plasmid after transmission of R plasmid its increases the resistance capacity of normal microbiota. This is the significance of normal microbiota that harbours an R PLASMID.
There are three common and principal types of polysaccharide, these are the cellulose, starch and glycogen. They are<span> all made by joining together molecules of glucose in different ways.
