Is it accurate to see boys and girls?

Is it accurate to see boys and girls? Many people want to know whether their baby is a boy or a girl after pregnancy, but having a boy or a girl is determined by genetic chromosomes. Some people will judge by the appearance of boys and girls, so is it accurate to have boys and girls?

It is said that it has a history of more than 300 years, which was invented by a scientist in our country. It is mainly based on five lines of gossip deduction of Yin and Yang and time calculation. Now science has denied the accuracy of giving birth to boys and girls, but there are still many expectant mothers who are eager to know the sex of the fetus by giving birth to boys and girls.

It is difficult to study the authenticity of the appearance of boys and girls from the Qing Dynasty, but the painting method of boys and girls is clear at a glance. According to the lunar calendar algorithm, it is clearly listed that 18 to 45-year-old women will get pregnant in different months and give birth to boys or girls. Women can only control the birth of boys or girls by "planning" pregnancy every month.

Experts said that the so-called secrets of the Qing palace can only be regarded as a statistical table at best, without any scientific nature. To sum up, having boys and girls is only a matter of probability. There are 23 pairs of 46 chromosomes in human cells. Comparing the chromosomes of men and women, it is found that 22 pairs (44 chromosomes) of men and women are the same. These identical chromosomes are called autosomes. The remaining pair is a very special chromosome, and the male and female chromosomes are combined in different ways. Y chromosome is very small, about one third of X chromosome. The XY chromosome is called the sex chromosome. Such a small difference in chromosome combination makes us different genders.

Theoretically, the number of boys and girls should be 50% each, but in fact, there are about 5 1.3 boys and 48.7 girls per 100 newborn, and the ratio is roughly the same in all countries. There will always be more men than women in society. Scientists have given a very vivid explanation for this phenomenon. Y chromosome is smaller and lighter, so it will run faster and have a chance to combine with eggs faster. Therefore, the combination of two X chromosomes or one X chromosome and one Y chromosome cannot be controlled artificially.

The table of boys and girls consists of two parts, the abscissa is the month of pregnancy, from 1 to 12, and the ordinate is the age, from 18 to 45. This table 1 to 12 represents the month of pregnancy, and 18 to 45 years old refers to the age of pregnant women at the time of pregnancy, but remember that this table is calculated according to the imaginary age. If a boy or girl meets a leap year or a leap month, the first half of the month will remain unchanged, and the second half will be counted as next month. If it is April, the first half is April and the second half is May.
