I made "non-invasive DNA", and as a result, I didn't mention "sex chromosome" in the SMS notification. What happened?

The inspection reports received are 2 1, 18, 13.

Sex chromosomes refer to chromosomes carrying sex genes. Under normal circumstances, there are 23 pairs of chromosomes in each cell of human body, including 22 pairs of autosomes and 1 pair of sex chromosomes.

For humans and other creatures, the male sex chromosome is XY and the female sex chromosome is XX. Different combinations of the two have produced offspring of different sexes.

For some creatures such as chickens, the male is ZZ and the female is ZW, which is contrary to human beings. The most important thing is that no matter what kind of organism, the proportion of individuals who produce different sexes is the same, which is of great significance to maintain the balance of gender ratio.

Because of testicular hypoplasia, patients have low sexual desire because of insufficient androgen secretion. On the other hand, androgens can "burn" fat. Therefore, patients with Creutzfeldt-Jakob syndrome are rich in subcutaneous fat and their skin is not worse than that of women, which is why they are called "handsome guys".

Most patients with Creutzfeldt-Jakob syndrome have been infertile or have low erectile function, and they didn't realize that they had an extra X chromosome until two or three years after marriage. In fact, before puberty, patients and ordinary boys did not have too many abnormalities. Careful parents can find that their son is timid and has a high and sharp voice, much like a girl. After puberty, patients began to have obvious symptoms, and some people were even accused of being "false mothers" and "small white faces" because of their more serious symptoms, resulting in inferiority complex. .
