Evolutionary analysis indicated that TaSDIR1-4A has a close relationship with the homologous genes in rice (Figure S1c).nahaburep itrareb sutatum atak irad lasareb isatuM . Individuals with nullisomy are referred to as nullisomics. If the individual with polyploidy bears three sets of haploid chromosomes, the condition is said to be triploidy. `crossing over between chromosomes with inversions often leads to nonviable gametes, thus decreasing recombination frequencies`. A cell or individual with one chromosomal type missing, with a chromosome number such as n-1 or 2n-2. Tanaman tersebut diberi zat tertentu sehingga mengakibatkan terjadinya mutasi menjadi tanaman baru yang memiliki total kromosom 40.) chromosome.

The trans-acting effects of missing one or two copies of C2 chromosome were more pronounced than cis-effects for majority of involved genes. If a cell is missing one or more chromosomes, it is said to be aneuploid ( an - = not, "not good"). Pada kelainan ini, jumlah kromosom tetap sama 46 buah atau 23 pasang, namun ada kelainan pada strukturnya seperti: : ada satu atau beberapa bagian kromosom hilang.
