Final answer:
The XY chromosome pair is indeed indicative of a male, as typical females have XX chromosomes and males have XY chromosomes.
Step-by-step explanation:
The statement that the XY chromosome pair is male is true. In human genetics, sex determination is controlled by the combination of sex chromosomes individuals possess. Females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome is what typically determines male sex.
During sexual reproduction, male gametes, which are sperm cells, can carry either an X or a Y chromosome, corresponding to the 50% chance of producing a male or a female offspring when one of these gametes fuses with a female gamete (egg), which always contains an X chromosome. Rarely, individuals may have different combinations of sex chromosomes due to errors in meiosis, such as the XXY combination in Klinefelter syndrome or XYY seen in Jacob syndrome.
Thus, while the sex chromosomes XY define a typical male chromosome complement, variations can occur, leading to different genetic disorders or conditions.
