Development of Behaviour Flashcards
What instinctive behaviour
Genetically inherited behaviours that do not require learning and no developmental plasticity
How do European eels show learnt behaviour
Parents birth juveniles in Sargasso Sea and die
Juveniles make it home without parents
Must be encoded in genes
Explain the 90 min baby experiment
90 min year old babies shown face, config, linear and inverse
All respond to face and some to config
None response to linear or inverse
Shows babies have innate knowledge of human face
What does he alpha calcium calmodulin kinase gene do
Effect learning in mice
Which gene effects learning in mice
Alpha calcium calmodulin kinase
What gene effect circadian rhythms in Drosphila
Per gene
What gene affects maternal behaviour in mice
FosB gene
Explain the displaced pups experiments
Pups displaced in a line from mother
Normal mouse with normal fosB gene collected pups
Mutant mouse with mutant fosB gene left pups to die
What does the hTAS2R38 gene determine
Bitterness perception of glucosinolates
Explain results from the glucosinolates bitterness test
PAV/PAV sensitive - 60% more bitter than insensitive
AVI/AVI insensitive
PAV/AVI intermediate
Explain the snake test
Coastal garter snakes eat slugs
Inland garter snakes eat frogs
None of the subjects had eaten slugs before
Coastal subjects are slugs
Inland subjects rejected slugs
Shows is innate behaviour, not learnt
What do bees do age 0-5 days
Clean cells
What do bees do age 0-15
Feed larvae
What do bees do age 0-20
Feed nestmates
What do bees do age 10-20
Pack pollen
What do bees do age 10-25
Forage
What is the honey bee foraging gene
Amfor
How have experiments proven songs in birds are innate
Birds have been reared in acoustic isolation but still have a template for their song
What do make song sparrows learn in their first three months
The dialect of the population they’re in
If the bird is moved to a new population within those three months, it will pick up the new dialect
Which way do western blackcaps orientate
South west
Which way to eastern blackcaps orientate
South east
Which way do hybrid blackcaps orientate
South
How do scientists know which way blackcaps orientate
They put them in a cone covered in soot. The birds would scratch off the soot when trying to escape . The soot was scratched off in the direction they orientate
How do hybrid redstart probe migration time is genetic
Black redstarts leave late as don’t have far to travel
Common redstarts leave early as they have far to travel
Hybrid redstarts leave inbetween these time regardless of location
Is migratory behaviour modified with experience
Yes
How do migrating starlings probe migration can be adapted based on experience
When the starlings left their breeding grounds, some were sent to Switzerland by scientists rather than left to go to UK. The experienced starlings turned around and went back to the UK where as the juveniles carried on to Spain as they knew they had to go SW but didn’t know where as they hadn’t been there before
What is gene environment
Everything in the environment that affects that gene
What environmental factors effect genes
Other genes in genome
Cellular environment
Physiology of individual
Environment of individual
Explain the ornament bird experiment
When both parents were ornamented or just the father was, the female offspring preferred to mate with ornamented makes
When just the female was ornamented or neither parent, the female offspring didn’t have a preference when mating
