WebThe depression may be from very high to nil. Based on degree of depression, the plant species can be grouped into four broad categories. 1. High inbreeding depression Inbreeding leads to severe depression and exhibit lethal effects. After 3 or 4 generations of selfing it is hard to maintain lines. E.g. Lucerne, Carrot. 2. Moderate inbreeding ... WebDec 14, 2024 · Inbreeding depression is expected to play an important role in the establishment of neopolyploid lineages, their capacity to colonize new environments, and in the simultaneous evolution of ploidy and other life-history traits such as self-fertilization.
