r locus
1.In the r-t diagram, where t is the cosmic time and r is the radial co- ordinate defined as the proper radial distance divided by the scale factor, the locus of the incoming photon emitted at the big bang and reaching us now, r_(t), is a mirror image of the locus of the outgoing photon emitted at the big bang with r = 0, r+(t).
2.The result showed that AC is mainly controlled by two major QTL s located on chromosome 3 and 6 as well as five minor QTLs, the major QTLs were detected with LOD scores more than 8.0, and one on chromosome 3 is linked with R FLP marker R2170 and another on chromosome 6 is linked to R1962 that is closed t o wx locus.
