✦ Synopsis

The empirical coefficient of correlation and the empirical coefficient of regression were evaluated in New Zealand White rabbits between birth weight and crown-rump on the one hand and number of implantations and litter size on the other. The average birth weight decreases with increasing litter size (P = 0.01). The decreased supply of blood to the single fetus in big litters might be responsible for this result. As no definite correlation between crown-rump and litter size could be proved, the conclusion may be drawn that the crown-rump is more determined by genetic factors than is the birth weight.
