a gene on the X chromosome responsible for color vision

a gene on the Y chromosome that initiates male sex determination

Verified step by step guidance1
Understand what the SRY gene is: it is a gene involved in sex determination in humans and many mammals.
Recall that the SRY gene is located on the Y chromosome, which is one of the two sex chromosomes (X and Y).
Recognize the function of the SRY gene: it initiates the development of male characteristics by triggering the pathway for male sex determination.
Eliminate incorrect options by matching their descriptions with what is known about the SRY gene: it is not on the X chromosome, not mitochondrial, and not autosomal.
Conclude that the best description of the SRY gene is 'a gene on the Y chromosome that initiates male sex determination.'
