cell population phenotype decreased spore germination frequency decreased spore germination 2011-08-15T11:41:34Z Note that this phenotype is usually assayed by observing a population of spores and observing how many germinate. Also consider annotating to 'inviable spore (FYPO:0002151)' with an extension to indicate incomplete penetrance, especially if you have a quantitative measurement. midori decreased spore viability reduced spore germination frequency A cell population phenotype in which the frequency of occurrence of spore germination is decreased. spore germination: decreased reduced spore viability FYPO:0000581 abnormal phenotype
