Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.

Question

Why is the color blindness gene still common in today's population?

Expert Solution

Step 1 Introduction:

Color blindness: It is a genetic disease caused due to mutations on the X-chromosome. color blindness is caused by a fairly common X-linked recessive gene. Color blindness is more numbers in males than females as males have only one X-chromosome which expresses its character but in females presence of two X-chromosomes mutations in one chromosome is suppressed by second X-chromosome.

The difference in X-chromosome characters can be seen in the decreased number of light-sensitive cells found in the retina of the eye. These cells are called cones that sense wavelengths of light and enable the retina to distinguish between colors.
