A comment on Xie and Xu: 'mapping quantitative trait loci in tetraploid species'

Genet Res. 2001 Oct;78(2):187-9. doi: 10.1017/s0016672301005262.


Xie & Xu (2000) present a model for mapping quantitative trait loci in an autotetraploid population. However, one aspect of their model, namely gamete formation, does not properly represent the biological process in autotetraploid species. This paper gives a more realistic formulation for this part of the model, and discusses the consequences for multipoint mapping.
