11. The selective advantage of outcrossing appears to be the masking of deleterious recessive mutations. 12. They also have a high outcrossing rate, which helps to increase genetic diversity. 13. Arrangements other than hermaphroditic help to ensure outcrossing . 14. "Xerocrassa geyeri " is hermaphroditic species and fertilisation is obligately outcrossing . 15. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. 16. A study was conducted to estimate the amount of outcrossing under local conditions in Malaysia. 17. Outcrossing between unrelated individuals results in the beneficial masking of deleterious recessive mutations in progeny.18. Outcrossing as a way of avoiding inbreeding depression, has been especially well studied in birds.19. Assessments of the mating system of this species have found that outcrossing rates vary between populations. 20. "' Outcrossing "'is where two unrelated individuals are crossed to produce progeny.
