Explanation:
Detailed explanation-1: -A particular species of shark normally reproduces sexually. In captivity, it was found that a female could also reproduce asexually. What is ONE negative result from asexual reproduction? decreased (less variation) biodiversity within the species.
Detailed explanation-2: -Polyembryony is a widespread form of asexual reproduction in animals, whereby the fertilized egg or a later stage of embryonic development splits to form genetically identical clones.
Detailed explanation-3: -Since sharks have an XY sex determination system, all parthenogenetically derived offspring are female, XX.
