#5. Developmental Biology
Programmed cell death, or apoptosis, is an
essential part of animal development. In the nematode, with its invariant cell
lineage, particular cell lineages or particular cells within specific lineages
are destined to end in programmed cell death, and it was this feature that
allowed the identification of the process and the analysis of its genetic
control.
Which of the following combination of genes are correct?
