In fact, four-dimensional color Doppler ultrasound is a kind of "abnormal ovulation". Although it is not a mandatory item, during the 22-28 weeks of pregnancy, the abnormal ovulation examination must be done, and three-dimensional color Doppler ultrasound and four-dimensional color Doppler ultrasound must be selected, otherwise it will be too late to delay the fetal health examination!
Four-dimensional color Doppler ultrasound once in 24 weeks, I saw pregnant women photos in distress situation and lamented that her husband's genes were too strong.
Yesterday, I accompanied Xiaoqiu to the hospital for a four-dimensional color Doppler ultrasound. We went early, and it was Xiaoqiu's turn in less than half an hour. I thought it would take at least four or five times. I specially prepared chocolate and brown sugar water for her, and drank some to stimulate fetal movement when she failed the exam.
Who knows Xiaoqiu came out in less than half an hour and said to me cheerfully: This child is really funny! I quickly leaned over and asked her, what's the matter? So happy?
Xiaoqiu replied: I just saw the baby's four-dimensional photo, which is exactly the same as that of his father when he was a child. It's really interesting to see them from the Lao family.
I got the color photo report at noon, which is exactly the case! Although the face of the fetus is uneven, the nose is flat and the mouth is big, we can really see the appearance of Xiaoqiu's husband, which makes people sigh that this gene is too powerful.
? Why is the fetus in four-dimensional color Doppler ultrasound uneven, with a flat nose and a big mouth?
I don't know if you have noticed that almost all the four-dimensional color ultrasound photos of the fetus are potholes, with a flat nose and a big mouth, which all look ugly. Why is this happening? Is the fetus really that ugly?
In fact, these appearance problems are temporary, mainly because the fetal development is still immature.
The examination time of four-dimensional color Doppler ultrasound is 22-28 weeks of pregnancy, and it is still 12- 18 weeks from the "normal delivery" of the fetus. Not only is the fetal organ immature, but its appearance also has a lot of room for improvement. For example, the subcutaneous fat of the fetus does not accumulate, and the whole person looks very thin and wrinkled, and their face value will naturally be greatly reduced. The thick fetal fat on the fetus has not fallen off, which makes the fetal skin look bumpy and uncomfortable.
Moreover, the angle of the doctor's photo and the barrier of amniotic fluid will also affect the value of the fetus.
The purpose of four-dimensional color Doppler ultrasound is to eliminate deformity, not to take professional photos. In order to see the development of various parts of the fetus more clearly and do a good job of investigation, doctors will choose some unsightly angles to shoot, which will affect the face value of the fetus, resulting in a flat face, a flat nose and a big mouth. Moreover, in order to investigate more clearly, they will also zoom in and shoot some local features of the baby, which will also make the baby look strange.
Secondly, when taking pictures, there is a lot of amniotic fluid in the palace, which basically belongs to "underwater" shooting, and amniotic fluid will hinder shooting and cause deformation; The fetus may be more active, stretching his arms and kicking, burping and yawning, which will affect the shooting results.
? Although the fetus is ugly, the parents' genes are still there.
Although the fetus in the four-dimensional color Doppler ultrasound is ugly, the parents' genetic genes have always existed, just like the fetus in Xiaoqiu's stomach, just like her husband when he was a child.
So, what characteristics of the fetus are inherited from parents? These three characteristics are hereditary!
1. Parents' noses
The high nose is dominant and the flat nose is recessive.
If one of the parents has a big nose and a high nose, then the baby is likely to inherit this advantage and grow a handsome nose.
If both parents' genes are Aa (a dominant gene has a high nose and a recessive gene has a flat nose), then the child's gene may be AA/Aa/AA. If it is AA/AA, it means that the child will have a high nose; If it is aa, it means that the child will have a flat nose.
2. Parents' skin color
The baby's skin color generally follows the natural law of neutral color of "average after addition".
Generally speaking, parents with dark skin can't give birth to a baby with white skin.
If one parent's skin is white and the other is black, then the baby will be "averaged" in the embryo and then give the child a "neutral" skin that is neither black nor white. Of course, it may also be biased to one side. Take our family as an example. My mother's skin is particularly white, and my father's skin is darker. My skin is neutral, darker than my mother and whiter than my father, but my brother is different. His skin is whiter than my mother.
If the parents' skin is white, then the children's skin is not much black, and it will basically be similar to their parents.
3. Parents' eyes
Eyes are hereditary, and big eyes are superior to small eyes.
Except the size of eyes, the color of eyeballs, double eyelids and eyelashes can all be inherited. Take the color of the eyeball as an example. The color of eyeball follows the following rules: dark colors such as black and relatively light colors are dominant inheritance. Black is the most dominant color, so as long as one of parents' eyeballs is black, the chances of children's eyeballs being black will be very high.
PS: Unless parents have black eyes, one side is aa and the other is Aa, children are basically black eyeballs.
Double eyelids are also dominant genes. If both parents have double eyelids, children have a great chance of double eyelids. However, double eyelids have a characteristic, which may change with the age of children. According to statistics, the occurrence of double eyelids is only 20% in children, 40% in middle school students and about 50% in college students. In other words, many children are born with single eyelids, but with the growth of age, they become double eyelids.
? Martin's message:
As the old saying goes, "The Women's Congress has changed eighteen times, and the more it changes, the better it looks." In fact, not only girls, but also fetuses. When four-dimensional color Doppler ultrasound is used, the fetus looks really ugly. After their full-term delivery, their face value has obviously improved, but compared with other children, they are still ugly, like a wrinkled little old man; Don't worry, wait a few more months. After a full moon or a hundred days, the baby's face value will depend on the next level, killing many small fresh meat and fairies on the Internet.
