Discuss the evolution in hexaploid wheat.

Answer 1

Answer:

Spelt flour is derived from a distinct species of wheat that is hexaploid, having 6 copies of each chromosome, T. spelta. Unlike breadwheat, the grain of spelt wheat is not free threshing. It has been suggested that spelt wheat is a hybrid of the extinct tetraploid wheat T. parvicoccum diploid wheat T. tauschii.
