text: Among the genes that underwent pseudogenization, only ycf1 showed incomplete duplication (in the IRa and SSC junction region), the others – ycf68, orf42, and orf56 showed complete duplication in IRa/IRb suggesting a loss of function due to the accumulation of premature stop codons or truncations.
