Quizplus · Accepted Answer

The SRY gene on the Y chromosome is responsible for male sex determination. In individuals with a translocation of the SRY gene to an autosome of a 46,XX karyotype, the presence of the SRY gene causes male development despite having two X chromosomes. This condition is known as XX male syndrome. Therefore, the only option where a male phenotype can occur due to abnormalities in the SRY region is option B.
