How to split HapMap male sex chromosome genotypes?

[ymc]

Hi all

I downloaded HapMap r27 CHD chrX and chrY nr forward genotypes. But I don't know how to split them into X and Y haplotypes for male subjects. Can anyone help?

For example, in the CHD chrY file, the calls for male subjects NA17974 and NA17975 for four SNPs are:

rs6644970 AG AG
rs1132353 CT TT
rs553369 AT AT
rs3899157 CT CC

How do I split these four SNPs into two haplotypes? Thanks in advance.

Oh. I think I get it now. Thanks for reading.

entry 3 or 4 in these files lists the chromosome
