Answer: what are the domanit and ressesiv traits?
Explanation:
<u> Genetic bottle neck</u>
Explanation:
Genetic bottle neck is defined as an evolutionary event during which a population is drastically reduced to to a significantly smaller size within a short period of time.
A genetic bottleneck can result from various events such as natural disaster, hunting of a species to a point of extinction or habitat destruction to cause the death of large number of organism.
In the given situation a typhoon which is a type of natural disaster caused the population to reduce to a size of 20 individuals. Then we find that the allele frequencies were greatly changed and the allele for colorblindness became established.Hence, a large population of present day inhabitant are color blind.
So we can say that the population experienced a genetic bottle neck.
Answer;
-Electron microscopes can not view live cells because the method of preparation is lethal.
Explanation;
-The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
-There are many different disadvantages to using a electron microscope for example they are extremely expensive which limits the availability to use them. Furthermore researchers are unable to observe the image in color, as electrons do not possess color, which may not allow the image to be understood easily.
-Additionally the use of the electron microscopes require a large space for example a whole room which may not be feasible.
Answer:
The answer is letter C
Explanation:
The evolutionary mechanism most likely responsible for the difference between the two populations is natural selection.
The more closely related the organisms, the more similar the bond structures. Many mammals , for example, have similar limb structures. The rabbit is similar to the human arm, with a large upper bone "arm" (the arm in humans) and a lower part of two bones, a larger bone on one side (the radius in humans) and a smaller bone on the other side (the ulna). These species also have a collection of smaller bones in the wrist area (called carpal bones in humans) that lead to the "fingers" or phalanges
