The idea that induced change to aplant's genetic code is a phenomenon of the DNA age is also untrue: modern hexaploid wheat possesses six times as many chromosomes as its prehistoric ancestor, thanks to tireless selection and breeding over ten thousand years of human farming. (faith.org.uk)
Dwarf wheat has forty - two chromosomes (known as hexaploid), unlike einkorn wheat, possibly the oldest form of cultivated wheat, which has a simple genetic structure of fourteen chromosomes (known as diploid). (doctorakil.com)
As part of the international effort to sequence the 17 — billion — base - pair hexaploid bread wheat genome (2n = 6x = 42 chromosomes), we constructed a bacterial artificial chromosome (BAC)-- based integrated physical map of the largest chromosome, 3B, that alone is 995 megabases.
