11. His work focuses on epigenetics and understanding the impact of human genetic variation . 12. Natural selection for genomic imprinting requires genetic variation in a population. 13. Genetic variation is important for plant breeders to increase crop productivity.14. British populations lack detectable genetic variation , suggesting a strong founder effect. 15. This reduces natural genetic variation within the cropped varieties of plants. 16. Multiple Mating behaviour also plays a role in influencing genetic variation within populations. 17. Genetic variation is typically determined using DNA from peripheral blood leukocytes.18. Seedlings ( grown from hickory nuts ) will usually have sufficient genetic variation . 19. This is especially important in wheat with its low genetic variation . 20. A medical DNA database is a DNA database of medically relevant genetic variations .
