what is the minimum number of indivisals and SNPs for phasing haplotype?

Question

Hello all

as the title implies, how many individual and SNP be needed to haplotype phasing be accursed. as I understood , if I have a limited number of individuals per population and also SNP it caused phasing will be very inaccurate.I have 5 population with 400 to 1000 animal, I reconstructed haplotyped chr by chr.

Thanks a lot
