Moving in Tandem

Zhang Zian suddenly thought of Cathy's Abyssinian cat breeding manual. The contents within the manual were very difficult and technical. It made him regret returning all his biology knowledge to his junior high school teacher. Zhang Zian felt that Cathy sometimes deliberately took a longer detour in her breeding process when she could have taken a shortcut. Much like the mathematical sum of 1+(1x1-1x1), Cathy deliberately calculated the numerals in the brackets despite that it was absolutely fine to ignore them.

It was only at this moment that he realized how complex the genetic codes for cats' coat colors were. It was not as simple as 1-1=0. It would be silly of him to try to find shortcuts.
