What does the husband's chromosome mean for 46, XY, 22cenh+?
If a child has genetic defects, it is usually caused by dominant/recessive genetic defects or polygenic defects, which is very complicated and depends on the family history of genetic diseases. In short, if you are really worried about your child's problems, you should not just look at the chromosome status, but look at the genetic defects.
By the way, let me give you a brief introduction to the principle of fertilized egg formation.
The first meiosis of human body randomly forms a meiotic splinter cell (there must be 23 different ones) with only half chromosome genes. After hermaphroditic cells (sperm and eggs) combine, 23 pairs of cells with 46 chromosomes are formed, that is, fertilized eggs. At this time, giving birth to boys and girls depends entirely on sperm. Sperm with Y chromosome is a boy and generation X is a girl. Then the fertilized eggs are classified and differentiated normally, that is, they grow and develop into babies.
The problem will be that if the sex cell chromosome carries a dominant pathogenic gene, the next generation will also carry it. A typical example is a single double eyelid. Single eyelid is controlled by dominant genes, so parents with double eyelids have at least a 50%-75% chance of giving birth to a baby with double eyelids. This probability floating starring is to see if the parents' genes are pure nuclei.
It's a bit complicated. You can write wherever you want. Finally, I wish the baby health. If you don't understand anything, just ask me.
