Which human chromosome is most often linked to sex determination?
GeneticsSex chromosomes
Quick Answer
The Y chromosome is the chromosome most associated with male sex determination in humans. The SRY gene on the Y chromosome triggers male development in typical cases.
The Full Story
The Y chromosome is the chromosome most closely linked with male sex determination in humans. It carries the SRY gene, which usually initiates the developmental pathway leading to testes formation. Human sex determination is more complex than a single chromosome alone, but the Y chromosome is the key switch in typical development. It is much smaller than the X chromosome and contains far fewer genes.
Key Facts
1.The Y chromosome carries the SRY gene
2.It is much smaller than the X chromosome
3.It plays a central role in typical male development
