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)

One is unequal crossing over, in which recombination happens between different positions on chromosomes that are misaligned during meiosis. 

Another is replication slippage, in which the DNA polymerase loses its place and copies a segment of chromosome twice.
