We describe a new method of estimating the selfing rate (S) in a mixed mating population based on a population structure approach that accounts for possible intergenerational correlation in ...

We investigated the variation and short-term evolution of the selfing rate and inbreeding depression (ID) across three generations within a cedar forest that was established from admixture ca 1860 ...

“The way to think of (selfing) is it’s sort of like a holding-on strategy,” said LeBuhn, who was not involved with the study. Although increasing selfing does often lead to a decline in genetic ...

So selfing is not always an evolutionary dead end, since it can result in some offspring that may reproduce. Time will tell if the process may occur in vertebrates other than certain fish.

Thus, many flowering plants have mechanisms in place to prevent selfing, for example by recognising and rejecting their own pollen. Biologists refer to this as self-incompatibility.

More flowers are ‘selfing,’ scientists say. That could spell trouble for other species By Ayurella Horn-Muller, CNN Jan 23, 2024 Jan 23, 2024 0 ...

Results demonstrated that selfing in this species is possible, in that colonies in the solitary treatment produced viable larvae that successfully completed metamorphosis. On average, however, these ...

These acts of self-care made me feel empowered and liberated. Future-selfing depends on where your present self is, and like all therapy practices, it’s not a one-size-fits-all fix – and it’s not ...
