What did sutton observe about the relative numbers of chromosomes?

Sutton observed that the number of chromosomes in an organism is characteristic of its species and correlates with the complexity of the organism. He noted that during the formation of gametes, the chromosome number is halved through meiOSis, which is crucial for maintaining the species-specific chromosome count across generations. His work laid the foundation for understanding the role of chromosomes in heredity and the principles of genetics.
