The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density
than humans. An example is bacteria with gene densities ranging between 100 –
500 genes/Mb. Gene density is therefore
not a good characteristic in determining
the complexity of an organism.
Gene drives is a powerful genetic engineering technology that may help to eradicate diseases transmitted by mosquitoes but it may also be harmful and cause the extinction of natural populations.
<h3>What are Gene drives?</h3>
Gene drives refer to a genetic engineering strategy based on genome editing (e.g., CRISPR-Cas9) that allows to produce a bias in the inheritance patterns of natural populations.
Gene drives modify normal inheritance to increase the selection coefficient of genetically engineered individuals, which may result in an advantage to control a vector population.
In conclusion, gene drives is a powerful genetic engineering technology that may help to eradicate diseases transmitted by mosquitoes but it may also be harmful and cause the extinction of natural populations.

The answer is <span>They both suggest that snakes evolved from an ancestor with legs.
The second choice is not correct since we have no information about pythons and other snakes. We only have the relationship between geckos, snakes and legless eels. So, it is said that </span><span>snakes in general have more DNA sequences in common with four-legged geckos than they do with legless eels. This means that snakes are closer to geckos than the legless eels. We cannot conclude from this information which evolved from which, but we can say that </span><span>snakes evolved from an ancestor with legs.
In different case, if the snakes had more DNA sequence in common with legless eels, we would conclude that the snakes evolved from an ancestor without legs.</span>
