Males from Drosophila strains carrying P elements crossed to females that lack P elements P element becomes highly mobile in germ line of F1 hybrids Chromosome breakage reduces fertility in hybrids Progeny of F1 flies carry many new mutations induced by P element insertions. Embryogenesis three larval stages a pupal stage and finally the adult stage. Textbook Solutions Expert Tutors Earn.

During the ninth division cycle about five nuclei reach the surface of the posterior pole of the embryo. The drosophila life cycle The life cycle of drosophila from egg fertilization to adult life takes about 10 days at 25C. They are all artistically enhanced with visually stunning color shadow and lighting effects.

The nuclei then migrate to the periphery of the egg where the mitoses continue albeit at a progressively slower rate. Egg larvae pupa and adult present. The drosophila life cycle The life cycle of drosophila from egg fertilization to adult life takes about 10 days at 25C.
