An attempt to estimate the magnitude of additive genetic variation of body size in the guppy-fish, Lebistes reticulatus

摘要: Two experiments in Lebistes reticulatus were performed: a pilot selection experiment continuing for only two generations, and an designed to estimate heritability from the correlation between full half sibs. No response was obtained experiment. The character selected weight at 42 days. In second 63 days length 28, measured. this component of additive genetic variation significantly greater than zero demonstrated one characters, It not possible detect variance until part due environmental differences aquaria had been removed total variation.
