News Finding: "To be clear, our study does not suggest that having a particular combination of mitochondrial and nuclear genes would provide an advantage or a disadvantage," says Makova.
Paper Finding: 5) .
News Context: In the future, they plan to investigate this question and also to explore the effects of discordance on other aspects of mitochondrial function and on other complex traits such as the rate of heart disease. "To be clear, our study does not suggest that having a particular combination of mitochondrial and nuclear genes would provide an advantage or a disadvantage," says Makova. "But it does tell us that we should keep investigating these differences in geographic origin between these two groups of genes.
Paper Context: We found a significant enrichment in Native American ancestry at high-mt genes in Puerto Ricans, and a significant enrichment in African ancestry at high-mt genes in African Americans (Fig. 5) . Because Native American mtDNA haplogroups are more frequent in Puerto Ricans and African mtDNA haplogroups are more frequent in African Americans (Fig.
