Question GROUP A: Genetics Problems In humans, red-green color blindness is caused by a recessive allele on the X chromosome. A male with normal vision and his color-blind wife have a child. If the child is male what is the probability that he will be color-blind? The female in the previous problem has a daughter that is color-blind. The husband claims that this cannot be his child. Can you support or refute his argument?

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.
