Facts

  • If eggs develop mostly in males between 31.5 and 33.5 C, at 31.5 and 34 C the sex ratio is 50/50 (ref: ADW)
  • Males are smaller than females and reach puberty earlier (ref: Wiki)

Discussion

  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
