Verified step by step guidance

Understand the role of chromosomes in determining sex in mammals. Mammals typically have two sex chromosomes: X and Y.

Recognize that the presence of the Y chromosome is crucial for the development of male characteristics. It contains the SRY gene, which triggers male development.

Identify that females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY).

Consider the options given: X chromosome, Y chromosome, Chromosome 18, and Chromosome 21. Only the Y chromosome is directly involved in determining maleness.

Conclude that the Y chromosome is responsible for determining maleness in mammals due to its unique genetic content, including the SRY gene.
