The correct answer is 4.) Eventually they become separate species
A process of formation of a new species from an existing species is called speciation.
When a single species changed into two or more separate species, is called speciation. Speciation can take place due to reproductive isolation. In reproductive isolation, the separated species no longer can interbreed among themselves. This is happened due to mating differences, sterility or environmental barriers which finally results into the adaptive splitting into two species.
Answer:
Option-B
Explanation:
Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.
1. Total color blindness is not a rare disease in animals.
2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.
3. The red-green color blindness is more common than the blue-yellow color blindness.
4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.
Since all options except Option-2 are incorrect therefore option-2 is the correct answer.
