Genetic sequencing is a second way for a scientist to determine biological sex in both humans and animals (distinct from sexing). It became widely available and popular at the turn of the century. [2] Genetic sequencing also allows for the determination of rare genetic events when the y chromosome is incomplete and a male animal has female ...
