In humans, the allele for red-green color blindness is X-linked and recessive. An XY man with normal color vision marries a color-blind XX woman who gives birth to a XX color-blind daughter.  A] What is the phenotype and genotype ratios possible for a child born to this couple. B] What is the probability that the second XX daughter of this same couple will also be color blind? C] What is the probability that the next child this couple produces together will be a color-blind XY son? D] What can you tell me about the first color-blind daughter born?

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.
