Chromosome mapping with DNA markers.

New markers called RFLP's (for restriction-fragment length polymorphisms) can indicate the location on a chromosome of a disease-causing gene and serve to identify carriers. With enough markers one can map the human chromosomes--the first step toward an ambitious goal of molecular biology: sequencing the entire human genome.

A primary genetic map of markers of human chromosome 10.

We have constructed a primary genetic map for human chromosome 10 from 13 polymorphic marker systems defining 11 loci, using a new gene mapping algorithm implemented in the computer program GMS. The loci form a continuous genetic map that spans approximately 116 cM in males and 170 cM in females. These loci provide regularly spaced anchor points for linkage studies, except for one interval that is 28 cM in males and 64 cM in females.

A linkage and physical map of chromosome 22, and some applications to gene mapping.

A genetic map of human chromosome 22 has been derived from physical assignments and multilocus linkage analysis. It consists of the loci for the immunoglobulin lambda light-chain variable (IGLV) and immunoglobulin lambda light-chain constant (IGLC) regions, myoglobin (MB), the sis proto-oncogene (SIS), and an arbitrary probe (D22S1). The first RFLPs at the loci for SIS, IGLV, and MB are described.
