[Evaluation of the heritability of aldolase and actinomycin activity and heat resistance in the common frog].
The extent of heritability of activities and heat resistance of aldolase and actmyosin in the grass frog tadpoles and adults has been investigated. It has been found that for aldolase the heritability of heat resistance is rather high; almost half of the variability of the character falls on the genotype (h2=0.45). In the period of ontogenesis studied (42nd stage of metamorphosis) a distinct prevalence of the effect of the paternal heat resistance of aldolase was observed in tadpoles, whereas the maternal effect was negligible. The average heritability of actomyosin heat resistance for both the parents is close to that of aldolase, h2=0.43. The shares of the effect of each parent are similar. The heritability of actomyosin activity and that of aldolase is not statistically significant. It can be assumed that in some periods of ontogenesis, of major importance may be the paternal characters of heat resistance and enzyme activity, whereas in others--those of the maternal organism.
