Test of reliability of QTL for the phenotype of body weight of mothers (ID 10101) in rat models by sequential reduction of number of RI strains.

<p>The numbers on top of each figure indicate the number of Chrs. The numbers at the bottom of each figure indicate the megabases on the Chrs. Pink color lines indicate the level of significance and grey lines indicate the level of suggestive. The left figure on the top line shows the two major QTLs (Chr 2 and 16) were detected when the original 26 RI strains were used in the mapping. The right figure on the top line shows the genomic region of the peak region of QTL on Chr 2. The five figures on the second line show that both QTLs were detected when the strain number was reduced into 24. The rest figures of five lines (line 3 to 7) show the mapping results of the five replicates when the strain number was reduced into 21. The left figure on each of these five lines show the LRS level of QTL on Chr 2 and 16. QTL on Chr 2 reached the detectable level in each replicate while the QTL on Chr 16 did not reach the detectable level(the grey line) in replicate #1 (line 3) and 4 (line 6). Figures on the right of these five replicates show the peak region of the QTL on Chr 2 was mapped to the same location (between 162.5 Mb and 172.5 Mb).
