The PE is the proportion of the population, which has a genotype that contains at least one allele not observed in the mixed profile. The number of males fathering each clutch can be determined genetically and used to estimate the minimum BSR [ 1248 ]. The differential impact of polyandry on pre- and postcopulatory sexual selection reveals a fundamental difference in the way mating and fertilization success contribute to variation in male reproductive success.
Currently however, the magnitude highest sex ratio in india in Richardson the sex ratio skew in adults is unknown due to our limited understanding of the proportion of adult males and males approaching sexual maturity [ 11 ]. Featured college pages. Richardson Education.

Skin samples of approximately 1 mm x 3 mm were taken from the trailing edge of one of the flippers using a sterilized scalpel blade. Discussion The impact of polyandry on the way sexual selection operates on males has been debated for decades.
Another study examined in-water juvenile sex ratios of loggerheads and found a female to male highest sex ratio in india in Richardson, which was lower than the expected hatchling sex ratio [ 80 ].
