desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
