As the transition from G1 to S phase begins, CDK/cyclins recruit cdc45 and the GINS complex to the MCM helicase, which then becomes known as the CMG complex (Cdc45-MCM-GINS)

Ne = Male + Female  (when both are equal)

Ne = 4 × n(male) × n(female)/n(male)+n(female) 

(When both unequal Ne is smaller than then sum of both)
