Dictyostelium can utilize one of three survival strategies when food starvation-

Microcyst formation, favoured in dark & wet conditions, or ammonia levels are high.

Zygote formation, favoured in dark & wet conditions, & is triggered by ethylene produced by the cells.

Children with hereditary (familial) retinoblastoma inherit one defective copy of the RB gene 

(sometimes seen as a small deletion on one of the two copies of chromosome 13)
