SRP125268 PRJNA417993 Resequencing of additional five progeny in an F1 hybrid of Populus deltoides and P. simonii (II) We proposed a strategy for identifying gene conversion events in Populus with the next-generation sequencing (NGS) data from the two parents and their progeny in an F1 hybrid population. The strategy first involved in phasing the heterozygous SNPs of the parents to form the parental haplo-type blocks by NGS analytical tools, permitting to identify the parental gene conversion events with progeny genotypes.
