Can anyone explain the purpose of finding out the F2 generation?
Depends on the question. Generally to work out the alleles of the parents (by working backwards in a punnet square). Do you have a question on it? (Also, welcome to AN
)
Primate traits?
- colour vision
- pentadactylism
- mobile arms
- forward facing eyes
- warm blooded? Lots of animals are warm-blooded - not a primate thing
What about hominoid traits?
Anything else for the above?
From my notes:
Primates are distinguished by:
Opposable thumb on a 5-digit hand
Flat nails
Sensitive fingertips
Large, forward facing eyes
Colour vision
Protective bone at the outer side of the eye socket
Large brains compared to body size
Sexual dimorphism
Hominoids are distinguished by:
No tail
Molars with 5 cusps
Rip cage is flat not rounded
Locomotion by tree swinging, knuckle walking, or bipedalism
Posture is fully or partially erect, allowing use of hands
Hominins are distinguished by:
Bipedal
Fewer and smaller teeth
Flat face
Lack of heavy brow ridges
Large cranial capacity
Make tools
Use language and/or art
Are self aware
