SMALL POPULATION AND MUTATIONS. "The reduced effective population size allows deleterious mutations in functional sequences to increase in frequency in the population, or become fixed, causing deterioration of the sequences." https://lnkd.in/exrSaeb View in LinkedIn

THE KING. “It is the virus that is king of the jungle.” https://lnkd.in/guhpmyR View in LinkedIn

POPULATION IMPACT. "In genome regions with suppressed recombination, selection acting on either advantageous or disadvantageous mutations in the region affects all linked variants. This effectively restricts the size of the population, compared with the rest of the species’ genome, because some genotypes fail to reproduce. The effective population size can be considerably reduced for a Y chromosome that still carries many functional sequences." https://lnkd.in/exrSaeb View in LinkedIn

EVOLUTION. “Viruses are the leading edge of evolution.” https://lnkd.in/guhpmyR View in LinkedIn

EVOLUTION PATH. "If many adaptive changes occur when a chromosome in a co-sexual species evolves into a sex chromosome, this would suggest that trade-offs are common; that is, that these changes were maladaptive in co-sexual ancestors." https://lnkd.in/exrSaeb View in LinkedIn

BOMBSHELL. “We are the descendants of viruses.” https://lnkd.in/guhpmyR View in LinkedIn

RECENT EVENT. "The typically weaker sexual dimorphism in plants than animals may also be explained by the recent evolutionary origins of dioecy in most lineages." https://lnkd.in/ge7JD6J View in LinkedIn

PLANT DIMORPHISM. "The extent to which mate choice operates in plants also warrants special consideration because of the indirect ways in which plants reproduce as a consequence of their immobility. Indeed, the indirect nature of plant sexual interactions may be part of the explanation for why most plants show less extreme sexual dimorphism than animals." https://lnkd.in/ge7JD6J View in LinkedIn

PLANTS VS ANIMALS. "There are important differences in the biology of plants and animals that may provide insights into why and how the evolution of sexual dimorphism differs between these groups." https://lnkd.in/ge7JD6J View in LinkedIn

UNTANGLING ORIGINS. "If plants have evolved through the gynodioecy pathway, gynodioecious and dioecious species should co-occur in the same genera. It was found that, overall, angiosperm genera with both gynodioecious and dioecious species occur more frequently than expected, in agreement with the gynodioecy pathway." https://lnkd.in/guzeMTD View in LinkedIn
