By self-study, competition, and performance, two types of chromosome number variation can be recognized and counted, and the number of intracellular genomes will be calculated. Can draw the concept of diploid, polyploid, and haploid. 1.2 Competency goals Self-learning ability and computational ability through self-study and competition; training through competition and performance
