Table 2

Relative magnitudes of maternal and X-linked effects associated with each parental strain

X chromosome Maternal effect
Maternal environment
X effect−4.75+4.75
Interactions: maternal effect + X-chromosome effect
R+R or C+C+26.75 days
R+C or C+R−26.75 days
  • Calculated from untransformed IP data of F1 animals. Incubation period in days are shown in rows corresponding to their maternal environment (cytoplasm or uterine) and in columns corresponding to their X chromosome. The effects in days are shown in the final column (for maternal effect) and final row (X-chromosome effect). Below we indicate the effect of interaction between X chromosome and environment, calculated as described in Materials and Methods.
