Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.

A high pressure system has higher pressure at its center than the areas around it. Wind blows away from high pressure. Winds of a high pressure system swirl in the opposite direction. But a low pressure system - clockwise north of the equator and counterclockwise south of the equator.
Answer:
Answer is A. True.
Explanation:
Compartment syndrome is the condition which develop or occur through the increased pressure in the compartments or body space , most especially the legs and arms. This occur through some certain injuries like fracture, which causes bleeding in the muscle.
The only and best treatment for compartment syndrome is surgery.
In the case of Ms Hughes, she is believed to have developed a condition known as compartment syndrome, because patient with compartment syndrome, seem to continue to have increased pain despite the administration of morphine.And they keep complaining of unrelenting pain.
The correct answer is B) An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image.
