Zhang Lin and Little Five are discussing in the training room; whether Master Lagou can make a grand transformation hinges on this time.
"Look, this is the second gene test, and there are absolutely no issues. Tong Yongqian's kinship with his parents is fine," Little Five holds a thick stack of genetic analysis reports.
His father's sex chromosomes are the normal XY, and his mother's are XX. There is no extra Y chromosome, so given their genetic lineage, the disease-carrying gene is undoubtedly on the Y chromosome. Since that's the case with the Y chromosome, why did it pass from the maternal grandfather to his mother, and then through his mother to him?
The current gene detection report cannot reveal the underlying reasons because the more information we want to gather, the longer the time required, and the greater the workload. For instance, mapping the human genome requires many years and efforts of countless scientists from countries around the world to complete.
