The project intends to apply advanced genomics to two classic Australian systems and quantitative genetics to one to address long-standing questions about why asexual reproduction is rare. It aims to test for rapid changes in genomes accompanying hybrid-origins of asexuals and whether this new diversity enables their ongoing evolution. The significance is that support for this hypothesis would challenge current theory for why sex is so common. The expected outcome is to understand how variation is generated in natural populations with different ways of reproducing. Benefits would include significant contributions to global science, evolutionary training and potential applications in using hybridisation to manage threatened species or pests.

该项目旨在将高级基因组学应用于两个经典的澳大利亚系统和定量遗传学上，以解决有关为什么无性繁殖很少见的长期问题。它的目的是测试伴随着无性恋者的杂种基因组的快速变化，以及这种新的多样性是否能够促进其持续的进化。意义在于，对这一假设的支持将挑战当前的理论，为什么性如此普遍。预期的结果是了解如何以不同的繁殖方式在自然种群中产生变异。利益将包括对全球科学，进化培训以及使用杂交管理受威胁物种或害虫的潜在应用的重大贡献。
