A husband and wife have normal vision, although both of the couple's fathers are red-green color-blind, an inherited X-linked recessive condition. What is the probability that the couple's first child will be a normal son? Enter your answer as a fraction or a whole number. Hint: Remember, humans determine sex via the XX = female, XY = male system. Think about the probability of having either a son or a daughter and the probability of having red - green color blindness.

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.
