Final answer:
The statement is false as relatives can be connected through blood, marriage, or adoption. Societies vary in how they trace lineage, with bilateral descent being common in the U.S. The relationship between relatives impacts blood donation, with blood type and Rh factor determining compatibility.
Step-by-step explanation:
The statement 'Relatives Only Include Two Persons Related by Blood' is false. Relatives can include a wide range of connections through blood, marriage, and adoption. For example, a child's DNA fingerprint should match segments from both the mother and father to establish a biological relationship. In societies that follow paternal or maternal lineage exclusively, such as those with matrilocal or unilateral descent patterns, a child might be considered related to only one parent. However, in societies that practice bilateral descent, individuals trace their lineage through both parents' sides. The United States is an example of a society where bilateral descent is common. Therefore, concepts like extended family can include relatives from both the mother's and father's lines, spanning multiple generations.
Historically, before the ratification of the 19th Amendment, women were not considered a legal person on their own, which is true. This changed with the amendment, which recognized women's suffrage and legal personhood. Regarding family relations, research suggests that people generally feel their current family unit, which could be a nuclear family or an extended family, is at least as close, if not more close than those they grew up with.
In terms of blood donation, being related does not automatically qualify or disqualify someone from giving blood to another family member. Compatibility depends on the blood types and Rh factors of the donor and recipient. The D antigen is not part of the ABO blood group system; instead, it's part of the Rh blood group system, and its presence or absence can lead to complications like hemolytic disease of the newborn, which is more likely in subsequent pregnancies due to the mother's immune system response to Rh-positive fetal blood.
