The Origins of Sex
Sex was invented around 2 billion years ago with the emergence of eukaryotes, involving the fusion of gametes like eggs and sperm. This process, known as meiosis, allows for genetic recombination, creating diversity in offspring. Unlike bacteria, which utilize different mechanisms for genetic exchange, eukaryotes have a complex system that has remained largely consistent across various life forms.In this clip

In every gamete produced by an organism, is the combination of genes — the same because it is created from the same DNA - the same because chromosomes are copied prior to meiosis - different due to DNA replication prior to mitosis - different due to the genetically unique gametes produced during meiosis?
