Facts

  • A pregnant female is capable of extending her gestation period by up to 2 weeks if the start of the summer rains are latewhich will result in poor grazing value and thus poor nutritional value of her milk produced (ref: wildlife)

Discussion

  • Males are assumed to differ from females by {p_Am} only
  • Slow foetal development is assumed
