Quizplus · Accepted Answer

The presence of a Y chromosome typically results in male development, indicating that it carries the genes necessary for male sex determination. This is evident from the fact that individuals with XXY genotype are phenotypically male, demonstrating the Y chromosome's role in conferring maleness regardless of the number of X chromosomes.
