lethal - all die during embryonic stage | maternal effect
some die during embryonic stage | maternal effect
muscle cell of ptilino-pharyngeal muscle 18a | maternal effect
muscle cell of transverse-ptilinal muscle 18b | maternal effect
Some adult escapers. Slow degeneration of muscles, fibres enter the fragmentation step but are not readily absorbed. Delay cell death of the ptilinal muscle.
