Phade,

Ask that question to any statistics professor that and they will disagree with you. 52% of a sample within a prescribe error rate supports 50/50. If you want to discuss the Z score and standard deviation formula we can at great length.

I did just buy "The Deer of North America" by Leonard Lee Rue and on page 250 he discusses the ratios of the sex of fawns. He suggests that sex ratios are determined by the quality of the habitat.His ratios were never 50/50, even statically. The swing in higher buck birthing rates or higher doe birthing rates is quite pronounced. Very interesting reading.
