cell population phenotype increased conjugation frequency A cell population phenotype in which a larger than normal proportion of cells in the population undergoes conjugation. 2012-01-18T03:03:19Z increased occurrence of conjugation increased zygote formation midori Note that this term refers specifically to conjugation, whereas experiments that measure mating efficiency often do so by counting zygotes plus asci, sometimes also including spores. For such experiments, we recommend using 'increased mating efficiency' (FYPO:0001043). increased mating frequency increased conjugation efficiency FYPO:0000761 abnormal phenotype
