Selection efficacy at intraspecific and interspecific scales: insights from haplo-diplontic plants

Natural selection is a pillar of evssNatural selection is a pillar of evolutionary biology: it tends to fix beneficial mutations and remove deleterious ones. But the factors that determine selection efficacy are yet poorly understood. A proposed factor is the interaction between mutations? dominance and ploidy level: recessivity should reduce selection efficacy in diploids but not in haploids. Methodological limits make this challenging to test in species with a diploid-dominant life cycle. Yet, a whole phylogenetic clade under-explored in genomics gathers all the attributes to tackle this question: Bryophytes. Their life cycle is characterized by alternating a long haploid phase…
