Determination of haplotypes based on genotype data of 2 SNPs

Question

[Apprentice]

Hi.

I would like to determine haplotypes based on genotype data of 100 patients with 2 SNPs.

I know that PHASE software can determine haplotypes based on genotype data of many SNPs. Can this software determine haplotypes based on genotype data of two SNPs?

If it is impossible. Could you tell me other software that can determine it.

With two SNP sites, you could calculate the linkage disequilibrium between them in your population, that is, the deviation of the association between these two sites from the expected frequency when the two sites are independent.

Thank you for your advice. But I would like to know how to determine haplotypes for each individual. Could you give me any advice about it?
