In humans, a dominant allele controls the formation of a cleft chin, a Y-shaped fissure in the chin caused by an atypical bone formation in the mandible (this phenotype is also known as a chin dimple). A survey of 1200 college students found that 108 of them did not have a cleft chin. What was the frequency of heterozygotes in that student population?

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.
