The male map

Note: Red highlights refer to microsatellite markers, blue to EPIC markers, green to SSCP markers and pink to SNP markers.

 

The female map

The haploid chromosome number of P. monodon is 44 and hence additional linkage groups need to be identified to obtain complete genome coverage. In addition, it is likely that some of the existing linkage groups will coalesce as more markers are added.

However, progress is now likely to be rapid as there are already sufficient markers that new markers are incorporated into the map at a rapid rate.
