This analysis explores the distribution of blood types in the U.S. population, revealing that Type O is the most prevalent blood type. Additionally, approximately 85% of the population has a positive Rh factor, while 15% maintains a negative Rh factor. The study illustrates that O- blood can be transfused to 100% of individuals, whereas AB+ blood can only be used for 4%. Furthermore, it explains the genetic impossibility of a person with O+ blood having two O- parents, and the constraints on potential offspring's blood types.

  2. p. 320 Analyzing Data 1, 2, 3, 4 1. Which blood type makes up the greatest percentage of the U.S. population? 1. Type O+makes up the greatest percentage of the U.S. population. 2. What percentage of the total U.S. population has a positive Rh factor? What percentage has a negative Rh factor? 2. 85% of the population has a positive Rh factor and 15% of the population has a negative Rh factor.

  3. p. 320 Analyzing Data 1, 2, 3, 4 3. Which blood type can be used for transfusion into the largest percentage of individuals? Which type has the smallest percentage of possible donors available? 3. O- can be used for 100% of individuals but AB+ can only be used for 4%. 4. Could a person with O+ blood have two parents with O- blood? Could that person have a daughter with AB+ blood? Explain your answers. 4. No, a person with O+ blood could not have two parents with O- blood because both parents would be homozygous recessive for the Rh factor. They do not have any Rh+ alleles to pass on. This person could not have an AB+ daughter because a person with O+ blood only has O alleles to pass on.
