Final answer:
Recent research on sexually involved couples indicates that genetically similar couples are more likely to have reproduced. The corret answer is C.
Step-by-step explanation:
According to recent studies on sexually active couples, genetically similar couples are more likely to have reproduced. This means that couples who share similar genetic traits are more likely to have children together compared to genetically dissimilar couples. Factors such as genetic compatibility and shared traits can increase the likelihood of successful reproduction.
The research mentioned does not directly correlate genetically similar couples with a higher likelihood of marriage, reproduction, or lower rates of divorce. It does, however, provide other insights into factors influencing divorce and family dynamics. One such insight mentioned is that married couples with twins or triplets are 17 percent more likely to divorce than those with single births. There is also evidence suggesting that divorce has not discouraged children in their views on marriage and family, with many valuing strong marriages and believing in lifelong partnerships. The corret answer is C.
