Answer:
Stabilizing selection results in a decrease of a population 's genetic variance when natural selection favors an average phenotype and selects against extreme variations. In directional selection, a population's genetic variance shifts toward a new phenotype when exposed to environmental changes.

<span>Lafora disease is the most severe teenage-onset progressive epilepsy, a unique form of glycogenosis with perikaryal accumulation of an abnormal form of glycogen, and a neurodegenerative disorder exhibiting an unusual generalized organellar disintegration. The disease is caused by mutations of the EPM2A gene, which encodes two isoforms of the laforin protein tyrosine phosphatase, having alternate carboxyl termini, one localized in the cytoplasm (endoplasmic reticulum) and the other in the nucleus. To date, all documented disease mutations, including the knockout mouse model deletion, have been in the segment of the protein common to both isoforms. It is therefore not known whether dysfunction of the cytoplasmic, nuclear, or both isoforms leads to the disease. In the present work, we identify six novel mutations, one of which, c.950insT (Q319fs), is the first mutation specific to the cytoplasmic laforin isoform, implicating this isoform in disease pathogenesis. To confirm this mutation's deleterious effect on laforin, we studied the resultant protein's subcellular localization and function and show a drastic reduction in its phosphatase activity, despite maintenance of its location at the endoplasmic reticulum.

Organisms from all six kingdoms have DNA but some are not enclosed inside the nucleus but scattered in the cytoplasm.Only eukaryotes have nuclei where DNA strands are enclosed.
Answer:
This nucleus then acquires <u><em>one </em></u>electron to become electrically neutral.
Explanation:
Fusion :It is nuclear reaction which two or more than smaller nuclei combines together to form heavy nuclear.
A neutron combines with proton in order to make heavy electron that is fusion reaction is taking place.
The overall charge in the nucleus will be +1.And in order to neutralize this positive charge the nucleus will acquire single electron to become electrically neutral.
