In an admixed population, these causal variants will occur more frequently on chromosomal segments inherited from one or another ancestral population.

The conservation of large chromosomal segments makes comparison between species possible and worthwhile.

There is therefore a pronounced increase in the number of chromosomal segments inherited from C57BL/6J.

Finally, genome wide scan's of Tajima's D in sliding windows along a chromosomal segment are often performed.

In due course, this will assist in introducing specific chromosomal segments from one cultivar to another.

Chromosomal inversions: reversing the orientation of a chromosomal segment.

These sites, unlike P elements, can be specifically inserted to flank a chromosomal segment of interest, aiding in targeted transgenesis.

For both Sets, we needed to identify new, high quality STRPs within specific, relatively small ( 1 mb) chromosomal segments.

Weaknesses in certain chromosomal segments left us vulnerable to a host of maladies; these new mutations proved elusive to identify and fix.

At a higher level, large chromosomal segments undergo duplication, lateral transfer, inversion, transposition, deletion and insertion.
