I am interested in determine the sex ratio of selected species of seabirds at hatching, fledging
and breeding stage. I have preliminary evidence (from external measurements-I
can't sacrifice birds) that sex if biased towards males, but I need to know
how the bias is distributed along age classes and how it is related to the life
story of the species.
Do you can point me to a reliable method of sex determination based on
chromosome staining? Please respond to jc at apeco.pe
