• Fatuoid aberrants may arise through whole or part deficiency of chromosome C9 which carries genes for the grain characters of cultivated oats and for meiotic synapsis. They are classified into three types by their particular chromosome constitutions and genetic segregation ratios (%) as follows: Het. Fatuoid Segregation 2n Configuration Normal Het. Hom. fatuoid Type I 42 20"+C9" 28:50:22 Type II 41 20"+C9 3:45:52 Type III 41+fr 20"+C9C9S 28:54:18Nullisomic hom. fatuoids of type II are asynaptic, dwarf and completely sterile. The long-arm (C9L) of chromosome C9 carries genes for the the cultivated type grain characteristics and its short-arm (C9S) bears a gene controlling synapsis.
