The viability of Drosophila melanogaster was measured in three conditions: (1) of eggs from parents living at different gravity levels (1-5 g), developed at 1 g; (2) of eggs from parents living at 1 g, developed at different gravity levels, and (3) of eggs developed at the gravity at which their parents were kept. Hypergravity (HG) decreased viability to a low extent in all three cases (75% of emergence in the worst case). The effects of keeping parent flies in HG and of growing their offspring in HG were not cumulative. The results are discussed in relation with Pearl's rate of living theory.
（1）来自生活在不同重力水平（1 - 5g）的亲本的卵，在1g条件下发育；（2）来自生活在1g条件下的亲本的卵，在不同重力水平下发育；以及（3）在其亲本所处重力条件下发育的卵。在所有这三种情况下，超重力（HG）都使活力有一定程度的降低（最坏情况下羽化率为75%）。将亲本果蝇饲养在超重力环境中以及让其后代在超重力环境中生长的影响并非累积性的。结合珀尔的生活率理论对结果进行了讨论。
