This paper presents a study of intertemporal propagation of distributional properties of phenotypes in general polygenic multi-gender inheritance models with sexand time-dependent heritability. It further analyzes the implications of these models under thick-tailedness of traits’ initial distributions. Our results suggest the optimality of a flexible one-sex/two-sex mating system. The switching...
Gracilaria chilensis is distributed in New Zealand (including Chatham Island) and South America. This species has a three-stage sexual life cycle, as well asexual vegetative reproduction, commercially important it valuable source for producing agar. However, basing the crops exclusively on clonal reproduction propagation led to reduction their genotypic diversity, an increase susceptibility inf...
Stolons and rhizomes are modified stems for vegetative reproduction. While stolons grow above the ground, beneath ground. maintain genotypes of hybrids hence invaluable agricultural propagation. Diploid strawberry is a model studying stolon development. At axillary meristems, gibberellins MADS box gene SOC1 promote formation, while DELLA repressor inhibits Photoperiod regulates formation throug...
Transitions from sexual to asexual reproduction are often coupled with elevations in ploidy. As a consequence, the importance of ploidy per se for the maintenance and spread of asexual populations is unclear. To examine the effects of ploidy and asexual reproduction as independent determinants of the success of asexual lineages, we sampled diploid sexual, diploid asexual, and triploid asexual E...
Sexual reproduction is both extremely costly and extremely common relative to asexuality, indicating that it must confer profound benefits. This in turn points to major disadvantages of asexual reproduction, which is usually given as an explanation for why almost all asexual lineages are apparently quite short-lived. However, a growing body of evidence suggests that some asexual lineages are ac...
