A sandblasted rock could be different in color because sandblasting takes the top layer of the rock (which has been weathered) off.
The process in which any population people choose their mates according to their preferences is known as assortative mating.
Example:
- A short height women to mate or marry with short man.
- A long height man wants to marry a tall women.
So, the tendency in which individual wants to mate those individual who are similar to them is called assortative mating.
Answer:
Inbreeding
Explanation:
The offspring from mating of individuals in a close group can cause inbreeding. The genetic disorders present in both mates will pass along the offspring without the possibility of correction, causing genetic abnormality.
The inbreeding can occur naturally in a way to guarantee the propagation of the offspring. The result of this mating is the increasing of homozygous, which can result in lack of variancy. By the other hand, it can enhance a similar characteristic as well as a genetic problem.
For example, in a crop of clones organisms a disease which has affected one crop can spread more easily through the community of clones than non-clones crops of the same specie.
The probability of any outcome of a random phenomenon is the proportion of times the outcome would occur in a very long series of independent repetitions.
