Explanation:
Detailed explanation-1: -The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.
Detailed explanation-2: -Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes. However, there are exceptions to this rule. The sex chromosomes determine the sex of offspring.
Detailed explanation-3: -Normal human spermatozoa carry either the X or the Y chromosome. The differences between X and Y spermatozoa (X and Y haploid cells) may exist in two areas: the different chromosomes (i.e. different kinds and numbers of genes) and the different sperm structures and functions (i.e. different genetic expression).
