TEA [102]

It is an example of directional selection.

The different kinds of natural selection can influence the distribution of phenotypes within a population. In stabilizing selection, an average phenotype is preferred.

In directional selection, a modification in the surrounding changes the spectrum of the observed phenotypes, and in diversifying selection the extreme values for a trait are preferred over the transitional values. This kind of selection usually pushes speciation.

The directional selection, in the field of population genetics, refers to a mode of natural selection in which an extreme phenotype is preferred over other phenotypes, making the allele frequency to change with time in the orientation of that phenotype.

5 facts about the reproductive system
svp [43]
<span>After you ovulate, your egg is fertile for between 24 to 48 hours and a man’s sperm can survive in the female body for 48 hours. There have actually even been documented cases of live sperm surviving in the female reproductive system for eight days after intercourse!One breast is always larger than the other. Most of the time, it goes without notice but it is typical for breast size to be slightly mismatched. Some women can be born with two uteruses or two vaginas and have no idea until they notice abnormal menstruation or excessive bleeding. You are born with all the eggs you will ever have in a lifetime which can be anywhere from thousands to millions however, only about 300 to 400 of these eggs will mature and be released for fertilization. <span>You ovaries take turns each month releasing eggs.</span></span>
