fly and worm

Question 1

give ideal characteristics for a genetic analysis model

Answer 1

small organism, sequenced genome, easy to breed + score phenotypes, short generation time, large embryo batches

Question 2

what does adult fly from from?

Answer 2

imaginal discs

Question 3

how many somatic cells does adult c.elegans have?

Answer 3

959

Question 4

when does drosophila have AP and DV axis set up?

Answer 4

by time it is laid (set up in egg) maternal RNAs and proteins set up pattern in egg chamber

Question 5

what cleavage does drosophila have?

Answer 5

superficial - forms syncytial blastoderm which becomes cellular blastoderm when cellurisation occurs

Question 6

what lineage does c.elegans have?

Answer 6

invarient lineage - cell division and fates are same between individuals

Answer 8

yes they both do

Question 9

what techniques can be used on drosophila?

Answer 9

mutagenesis, transgenesis and clonal analysis
