The person should be a male.
Only male carries XY chromosomes, meanwhile female carries XX chromosomes. "Heterozygous for the X and Y chromosomes" means that the person have both X and Y chromosomes in their cells, therefore only males fits the description.
This is also why the birth rate of girl or a boy is always 50%, it is because the sex of a person is only determined by the sperm from a male. Each sperm either carries a X or a Y chromosome, never the both. Therefore, the chances of a X or a Y sperm fertilising an X egg is always 50%, also explains why both female or male must have at least one X chromosome because an egg always carry an X.
The rate of mitotic division that takes place between the 4-cells stage and the morula, is 12 hours per cell division. The first division occurs in about a day after fertilization, and subsequent divisions occur every 12 to 24 hours after that. The zygote divides several times to form a mass of cells called morula, which is an embryonic stage consisting of a solid, compact mass of 16 or more cells.
