From the book Thank You for Being Late by Thomas Friedman.
Let’s say you have two genomes. And genome A has one gene that is perfectly adapted for today’s system of cold and genome B has twenty genes, only one of which is expressed as resistance for cold. Genome A has one option to mutate the gene until it randomly hits on the solution to the problem or it dies. Genome B might have twenty offspring. Genome B has twenty potential answers. It will express or modulate each of those twenty, and there is a very good chance that one of them will be the right solution to the problem it faces.
What does “each of those twenty” refer to - twenty genes (genome B has twenty genes) or twenty offspring (Genome B might have twenty offspring)?
And is it possible to understand from the text what problem is meant here? Cold?
