Compared with morphological and life history traits, quantitative genetic variation of metabolic and related traits merlot redbud tree for sale in animals has been poorly studied.We used flow-through VC0(2) respirometry and simultaneous activity measurement on nymphs of the sand cricket {Gryllus firmus) from inbred lines to estimate broad-sense heritability of four metabolic variables.In addition, we measured a number of linear dimensions in the adults from the same inbred lines.

There were significant multivariate effects of inbred lines for all traits and broad-sense heritability for physiological traits was 4.5%, 5.2%, 10.

3% and 8.5% for average, resting, minimum and maximum C0(2) production in nymphs, respectively.Though the MANOVA indicated significant genetic variation among inbred lines in adult read more morphology, the broad-sense heritabilities were relatively low ranging from 0-18%.

Our results indicate that the heritabilities of metabolic measures are large enough to potentially respond to selection.
