Genetically Controlled Sex Determination:
Two common mechanisms: XX-XY system and ZZ-ZW system.
XX-XY system: Males have one X and one Y chromosome, while females have two X chromosomes (e.g., humans).
ZZ-ZW system: Males have two of the same sex chromosomes (ZZ), while females have two different sex chromosomes (ZW) (e.g., birds).
Other complex systems exist in various species.
Understanding these mechanisms is crucial for studying sex-related traits in genetics.
