Bibcode : Sci Restraining cages were placed over the nest chamber approximately 45 days after oviposition. Our result indicates that the number of males contributing to this population of nesting females is higher than would be expected from female-biased primary sex ratios alone [ 63 — 65 ].
To this end, paternal genotypes were identified through exclusion analysis and were used operational sex ratios in Jersey City estimate the number of males contributing to this population. Critical approaches to sex determination in sea turtles.

For species where the cost of successfully raising one offspring is roughly the same regardless of its sex, this translates to an approximately equal sex ratio.
