Cleavage - Drosophila

•FIRST CYCLES ,•Vade.M. movie of cellularization

Drosophila – 2 lectures

• Move on to gastrulation, organogen., metamorph.

• Once we know the embryo, meet the molecules• Because this is a largely ‘solved’ system

• Because these genes have key roles in all metazoans

All animals have related developmental histories
