Royal Society Open Science, 2021 The propulsion of sperm cells via movement of the flagellum is of vital importance for successful fertilization. While the exact mechanism of energy production for this movement varies between species, in avian species energy is thought to come ...

Review: Balancing Selection for Deleterious Alleles in Livestock
Frontiers in Genetics, 2021 Harmful alleles can be under balancing selection due to an interplay of artificial selection for the variant in heterozygotes and purifying selection against the variant in homozygotes.

Evolution; international journal of organic evolution, 2021 Darwin spent years investigating the effects of self‐fertilization, concluding that “nature abhors perpetual self‐fertilization.” Given that selection purges inbred populations of strongly deleterious mutations and drift fixes mild mutations, why does ...

Animals, 2022 Heterosis is a widespread biological phenomenon in fishes, in which hybrids have superior traits to parents. However, the underlying molecular basis for heterosis remains uncertain.

Peer Community in Evolutionary Biology, 2022 Most mutations affecting fitness are deleterious and they have many evolutionary consequences. The dynamics and consequences of deleterious mutations are a long-standing question in evolutionary biology and a strong theoretical background has already ...

Peer Community Journal, 2023 Classical models that ignore linkage predict that deleterious recessive mutations should purge or fix within inbred populations, yet inbred populations often retain moderate to high segregating load.
