Question
Select all that applyRecently, almost 1000 African human genomes were sequenced, which revealed that Blank______.Multiple select question.African genomes contain more than 300 billion bases of DNA not found in the reference human genomeAfrican genomes contain more than 300 Mb of DNA not found in the reference human genomethere are substantial differences in genomes from different regionsthere is substantially less variation within African genomes when compared with the variation within North American genomes
Solution
The correct answers are:
- African genomes contain more than 300 Mb of DNA not found in the reference human genome
- There are substantial differences in genomes from different regions
The first statement is incorrect because the human genome is estimated to contain about 3 billion base pairs, not 300 billion. The last statement is also incorrect because it is well established that there is more genetic diversity within Africa than any other continent, due to the long history of human habitation in Africa.
