The correct answers are:

• there are substantial differences in genomes from different regions
• African genomes contain more than 300 Mb of DNA not found in the reference human genome

Explanation:

1. African genomes are known to have the highest genetic diversity compared to other populations. This means there is more variation within African genomes, not less, when compared with other populations such as North American genomes.

2. The genetic diversity in Africa also means that there are substantial differences in genomes from different regions within Africa.

3. The statement that African genomes contain more than 300 Mb of DNA not found in the reference human genome is correct. This is because the reference human genome is primarily based on non-African individuals, and thus does not capture the full extent of genetic diversity found in African populations.

4. The statement that African genomes contain more than 300 billion bases of DNA not found in the reference human genome is incorrect. The human genome is estimated to contain about 3 billion base pairs, so it's not possible for there to be 300 billion bases of DNA not found in the reference genome.
