Genetic recombination analysis of the Egyptian IBVAssuit-1-QX-EGYIBV-2024 strain built in the RDP4 software. Pale pink is a track of sequence with a recombination origin. Potential putative parents involved in the recombination events of strain IBVAssuit-1-QX-EGYIBV-2024 are color-coded as follows: The K1255-03 Korean isolate (GI-19), “variant strain" of accession number: AY790364 is a major parent with green colour. SC021202 GI XXII strain, Chinese isolate G1-22 (of GenBank accession no. EU714029) is a minor parent with violet colour. Additionally, Recombinant strain Assuit-1-QX-EGYIBV-2024 with yellow colour
