I am doing some phasing using SHAPEIT.

SHAPEIT takes a genetic map as input which shows:

"Recombination rates between SNPs are provided via a genetic map that specifies the genetic position of the SNPs in cM".

SHAPEIT has a link to a set of genetic maps for all autosomes (now broken, but found on wayback machine):

This genetic map has has for each autosome a 3 column text file with the following headers:

position, COMBINED_rate(cM/Mb), Genetic_Map(cM)

But no chromosome 23.

  1. Does anyone know where I could get a genetic map that has chromosome 23

  2. If not does anyone know where I might look to begin making my own?
