Grendel Genes

Grendels have 60 less genes than norns, these mainly to do with reproduction & sociality.
In the table,
red genes are absent from the grendel genome, yellow ones are merely different.

Reproduction

(grendels are sterile)
RECEPTORS become fertile if oestrogen high
receptive to sperm if sex drive
involuntary lay egg when progesterone
become fertile if testosterone high
EMITTERS reproductive am fertile, produce oestrogen
permanently produce testosterone
I am fertile, produce sex drive - male
I am fertile, produce sex drive - female
when pregnant produce gonadotrophin
when pregnant produce progesterone
REACTIONS gonadotrophin removed oestrogen
alcohol making females randy
adrenaline removes testosterone
adrenaline removes oestrogen
gonadotrophin breaking down
INSTINCTS when horny, push opposite sex = reward
when horny, pull opposite sex = reward
Sociality

(grendels are
violent and
anti-social)
STIMULI when tickled by creature, get angry not happy
03 00 00 01 02 50 00 FF 04 1C 30 28 10 00 00 00 00
when slapped by creature, gets bored instead of scared
05 00 00 01 04 80 01 FF 04 11 50 1B 29 1C 49 27 12
gets angry when hearing creature speech
0C 00 00 01 0B 2F 06 AF 04 1C 10 00 00 00 00 00 00
feel better when hear user speech
LOBES Lobes 3 and 7 are different
REACTIONS alcohol increasing aggression not sex drive in females
2D 00 02 07 01 44 01 00 02 0C 01 07 40
INSTINCTS (11 of this type) action when hear "verb" = reward
when crowded and run from creature = reward
  EMITTERS SEVEN DRIVES
different somatic muscle energy used
  REACTIONS hunger increased by using up glucose
1D 00 00 03 01 3B 01 00 03 3A 01 03 40
adrenaline removes glucose
adrenaline breaking down
hunger breaking down
7 INJECTIONS CHEMICALS
  HALF-LIVES different - hunger and vitamin A broken down slower
  STIMULI pose 48 (lay egg pose)
  PIGMENTS HAS NONE - should have 12

All this adds up to the sorry state of affairs for the original grendels.
I would highly recommend using the complete grendels (by Greg Poehlein, Lis Morris, and EttinTrix)
With the updated grendels by Jessica (install this second)

Then so they can breed use a Grendel World or add Grendel Friendly, so that they can breed and stop being excessively violent.
