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.

该项目旨在将先进的基因组学应用于两个经典的澳大利亚系统，并将数量遗传学应用于一个系统，以解决长期存在的问题，即为什么无性生殖是罕见的。它的目的是测试伴随着无性生殖的杂交起源的基因组的快速变化，以及这种新的多样性是否使它们能够持续进化。重要的是，对这一假设的支持将挑战目前关于性为什么如此普遍的理论。预期的结果是了解变异是如何在具有不同繁殖方式的自然种群中产生的。其好处包括对全球科学的重大贡献、进化训练以及在利用杂交管理受威胁物种或害虫方面的潜在应用。
