When sex ratios vary in a population, we estimate Ne as: Ne$=4($Nm Nf$)/($Nm$+$ Nf$)1)$ Calculate Ne for a population $5$ males and $5$ females$2)$ Calculate Ne for a population $1$ males and $9$ females$3)$ Calculate Ne for a population with $1$ male and $1000$ females$4)$ What is the overall effect of a highly skewed sex ratio on the effective population size Ne$?$
