Area of Science:

  • Evolutionary Biology
  • Population Genetics
  • Reproductive Biology

Background:

  • Gynogenesis (female-only offspring) is a known reproductive mode.
  • Androgenesis, where offspring inherit only male chromosomes, is less common.
  • The evolutionary dynamics and population consequences of androgenesis are poorly understood.

Purpose of the Study:

  • To investigate the conditions favoring the spread of androgenesis alleles.
  • To model the population-level consequences of androgenesis.
  • To identify factors influencing the risk of extinction due to androgenesis.

Main Methods:

  • Population genetics modeling was employed.
  • Models simulated the invasion and spread of rare androgenesis alleles.
  • Factors such as mating system and sex determination were incorporated.

Main Results:

  • Androgenesis alleles are predicted to frequently spread to fixation.
  • Fixation of androgenesis can lead to population extinction by eliminating females.
  • Extinction risk is higher in dioecious species, particularly with paternal apomixis and female heterogamety.

Conclusions:

  • Androgenesis alleles function as selfish genetic elements with a high extinction potential.
  • The rarity of observed androgenesis may be due to detection difficulty and high extinction rates.
  • Further research should explore species characteristics that may harbor androgenesis.
