    Just gotta learn about the wheat plant, then finished Mod 1, half way through Mod. 2 and still got 3 and 4 to go... niccce
    I just learned about the wheat today

    Triticum aestivum is the artifically selected modern bread wheat consisting of the genotype AuAuBBDD. Both domesticated and wild wheat have contributed to this genotype. Wild wheats are diploid, and grasses can undergo polyploidy to hold more chromosomes within their nucleus. The resulting bread wheat is hexapolid 6n=48

    First Wild Einkorn is domesticated by changing phenotype but not chromosome number to Einkorn-AuAu. This is bred with wild grass BB to from a sterile hybrid AuB. This undergos a mutation to double chromosome number AuAuBB.
    This is then crossed with goat grass DD
    Another sterile hybrid is produced of AuBD
    Another mutation occurs to double chormosome number. To become AuAuBBDD---> Modern wheat!

    I remembered...cool!

    That was revision well done
