The 2022 genetic study on modern English people, published by Nature, showed that the average English person is some combination of 25-47% Anglo-Saxon (some of that could have come from later Scandinavian influence because the Angles, Saxons and Jutes were really similar), 14-57% pre-Saxon Briton, and the remainder, if any, is filled by French influence from after the Anglo-Saxon invasion. The study also showed that people of 100% pre-Saxon Briton dna were buried in the same way that an Anglo-Saxon might be buried, with items indicating the same status as other Anglo-Saxons.
All of this means that the Anglo-Saxons came on large numbers, but they didn’t replace or genocide the natives. The two groups heavily mixed and the Britons in England assimilated to Anglo-Saxon culture. Then, probably at several points afterward, Frenchmen came in waves to further affect the English gene pool (Frankish migrants, the Normans, the Huguenots, etc.).
