Explanation:
The nucleus is a central placed organelle in eukaryotic cells. It is said to contain the "blueprint of life" known as the DNA. The DNA is a structure located in the nucleus of the cell that encodes information necessary for the growth and development of the organism.
This information encoded by the deoxyribonucleic acid (DNA) of the cell includes how the organism will reproduce, hence, DNA is called the blueprint of life.
Answer: The father determines the biological sex of a baby
Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.
What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
