A rare pregnant woman sincerely does not want to know the gender of her unborn child. The majority asks this question as soon as they find out about pregnancy. At a later date, you can find out the sex of the baby using an ultrasound scan, but at the initial stages there are also methods that allow you to make a prognosis.
Instructions
Step 1
To begin with, consider determining the sex of the child according to the parent group. Everything is simple here, just look at the table. Blood type Father
Mother I II III IV
I Girl Boy Girl Boy
II Boy Girl Boy Girl
III Girl Boy Boy Boy
IV Boy Girl Boy Boy
Step 2
Now let's look at a method called "New Blood". It is based on the knowledge of the different cycles of blood renewal in men and women. The blood of men is renewed every 4 years, of women - 3 years. According to this method, the child will receive the sex of the parent whose blood was renewed later. Let's give an example:
Mother born in 1982, full years 29
Father born in 1978, full 33 years
Divide the father's age by 4, we get 33: 4 = 8, 25
Divide the mother's age by 3, we get 29: 3 = 9, 66
Next, we look at the remnants of the division, and who has it more, the baby of this gender will be born. In our case, for the father it is 0, 25, and for the mother 0, 66, which means that the child will be born female.
