2
Drosophila
Well established genetics, complete genome, long history, short life cycle, polytene chromosomes, mutant analysis
3
Polytene Chromosome
Salivary glands of drosophila make DNA copies without mitosis - instead of one strand you get 1000 identical copies together; can see banding patterns and chromosomal puffs
4
C. elegans
nematode, established genetics, complete genome, life cycle 3 days, hemaphrodite, complete fate map (made with laser or stains tests), mutant analysis
5
Xenopus laevis
Vertebrate, external eggs, many large eggs, clear shell, gene expression system (can insert proteins etc)
6
Gallus domesticus
Amniote, external development, can make windows in egg; chimera studies: add some cells from different species and trace their development
7
Mus musculus
Mammal, short lifespan; genome sequenced, very similar to humans; lots of transgenics and knockouts
