What determines the sex of a person?
| August 3, 2021 | education
In order for a person to be born, an egg and a sperm cell are needed. The ovum always has an X chromosome, which both boys and girls have. But a sperm can have both an X and a Y chromosome. If a sperm carrying an X chromosome enters the egg, then the zygote has an XX set – a female child appears, and if the sperm carries a Y chromosome and penetrates the egg, then the child will have an XY set of chromosomes – there will be a boy. Consequently, the sex of the child depends on the sperm.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
