Headscratchers / Zeke's Pad

• So, what are the rules for this show being a World of Technicolor Hair?
  • Are the hair colours random or hereditary?
    • The Palmer family themselves make this hard to tell; Ida has purple hair and Alvin has blue hair, and out of their three children, only one has a matching hair colour. So, did Ike and Rachel get their hair colours randomly/through recessive genes, or does Ida have some 'splaining to do?
      • Their ancestors from "Model Family" show that members Raphael and Zack had red and green hair, respectively (which is likely where Ike and Rachel got their hair colours), but that just begs the question of where they got their hair colours genes from when Idina and Calvin have the exact same hair colours as Ida and Alvin (just swapped).
    • On the flip side, the Fritter family tree seems to be exclusively teal-haired. Why, then, do the Palmers have such a variety of hair colours, but not the Fritters?
  • Why does everyone have black eyebrows instead of them matching with their hair colour?
• What order do the episodes happen in, chronologically? Episode 2 contains a photo that wouldn't be taken until Episode 20, and Episode 13 somehow shows one of the ancestor characters from Episode 23 in the modern day.
