The present day effective population size, N₀, and maximum likelihood estimates of the population growth rate, β and θ, with central 95% probability intervals for each

Gene	β̂	β1	β2	θ̂	θ1	θ2	P (data)	N̂0	β̂/N̂0
SMCY	70	47.6	79.9	70	36.5	85.0	3.5  × 10−20	27,000	0.0026

Three genes	70	6.0	103.4	110	37.5	139.6	1.8  × 10−30	28,000	0.0025

θ is the rate for the entire gene. β̂/N̂₀ is the estimated growth rate per generation. The 95% central probability intervals for β and θ are (β₁, β₂) and (θ₁, θ₂) respectively.
