Its not genetics so much as spiritual death. The British empire has opposed the Will of God for 500 years by first breaking off from the Church so the king could commit adultery, then killing actually Christians, and finally creating a cult of jew worship to justify the fact that they were now no better than the muzzies they claimed to oppose. Britain has been *asking* for this outcome for centuries and now people who had nothing to do with the sins of the empire (namely spreading jew worship to the whole planet in the form of zionism liberalism, up to and including committing fratricide on their brother Saxons in Germany because they dared not want to accept the most idiotic form of governance in human history) are suffering for it. By continuously rejecting their Christian heritage, the British have destroyed anything that might separate from brute pagans like the muslims. Spiritual death precedes racial death, in every single civilizational collapse, a race has first forgotten *who* they are before they then forget *what* they are and sink into racial decline.
