The Effect of Polygyny on the Sex Ratio of Mice (Mus Musculus)
1 Department of Zoology and Entomology, Louisiana State University, Baton Rouge, Louisiana
Two series of polygynous matings in mice produced a total of 3430 young, 1803 females and 1627 males, giving a sex ratio of 90.23 : 100 which does not differ significantly from that of the average for the colony, 93.06, indicating that polygyny has no apparent influence on the normal sex ratio, but that high or low ratios are individual characteristics of certain males.
