Studies of Avian Sarcoma and Erythroblastosis (Strain 13). III. Effect of Chick Sex on Virus Susceptibility2

Abstract
This study of the sex susceptibility of the chick to the virus of avian sarcoma and erythroblastosis (strain 13) indicates that female strain 1 single-combed White Leghorns (Pennsylvania Farm Bureau Hatcheries) are more susceptible to this virus than are male chicks of the same strain. Data from three experiments indicate an average difference equivalent to 0.88 logarithms of virus between the sexes. Latent-period procedures were used in analysis of the data.
