Couples who are trying to conceive are eager to adjust to the best condition to ensure that they can have a healthy and smart baby.
Whether the baby looks handsome or smart depends largely on the genes of the parents, if you can say that you can have a pair of twins or dragon and phoenix fetuses on these basis, it must be a gift from God, and the parents will be overjoyed.
Twins, dragon and phoenix babies due to the high similarity of looks, can always get everyone's envy and attention, but also can trigger the pride in the hearts of parents and mothers, but some time ago, there was a pair of dragon and phoenix babies on the Internet after the unexpected popularity, but attracted netizens full of heartache.
Twins are popular because of "genetic eccentricity", and the hair volume is one with the father and one with the mother, and the gap is painful
The two babies in the photo are fair-skinned, both wearing strawberry-colored clothes, although the facial features are very similar, but everyone can still distinguish the differences between the two children at a glance.
One is the "Mediterranean hairstyle" and the other is the "small fresh hairstyle", which is difficult for many netizens to accept: why are the two babies born out of the same mother's womb so big.
Netizens once doubted whether the baby's father was a senior programmer, whether the baby's small age had experienced too much, and careful netizens wanted to explore the truth of the matter...
Under the continuous attention of netizens, the mother shared the child's later growth experience on the Internet, fortunately, the baby with less hair has also changed the "kiwi" hair texture in the later stage of development, and finally can be tied to a small braid, but compared with the sibling sister, the sister's hair volume can still be clearly seen as "insufficient".
Later, the mother posted a family photo, and everyone woke up after seeing the appearance of the father and mother, it turned out that it was not a maternal fetal genetic mutation, and the amount of hair caused by the twins was very different.
Instead, the genetic gene is eccentric, the sister with more hair follows the mother gene, and the sister with less hair follows the father gene.
It is this eccentric type of inheritance that causes the two children to have differences in hair volume, which is painful to look at.
Analysis: Is there anything to pay attention to the genetics of hair volume?
From the perspective of genetic genetics, the child's skin color depends on the average of the parent's skin color, while the thickness and sparseness of hair depends largely on the father's hair volume, especially hereditary hair loss, which is almost always passed on from man to woman.
If the father-to-be is bald, the remaining daughter does not have this problem, and the parents do not have to worry, but if they are born with sons, the probability of baldness will become greater, and even the father of the expectant mother may leave a 25% probability of his baldness to his grandchildren.
Therefore, those babies who are "bald" at birth have largely inherited the genes of their father or grandfather.
Why are they twins, some look alike, some are different?
One: The difference between homozygotic and fraternal
Identical twins refer to the general pregnant mother only released one egg and a small tadpole combined to form a fertilized egg, and then the fertilized egg will be divided into two, forming two embryos, the two chromosomes receive the same chromosomes and genetic material, the two embryos of the same sex, generally will look very similar, like a mold carved out.
Fraternal twins mean that the pregnant mother has two eggs combined with two small tadpoles, and then developed into two independent individuals, so that although the baby is conceived in the same mother's womb, there may be genetic differences, and it will look different after birth.
Two: Homotopy also has a case of genetic mutation
Although most identical twins look similar, it is not excluded that some special genetic mutations occur, which are related to the pregnancy habits and diet of expectant mothers.
If you want your child to inherit their own excellent genes, pregnant mothers must start from themselves, reasonably improve their diet, control weight, and supplement more vitamins.
summary:
The baby's genes depend largely on the parents, if you want to give birth to a pair of excellent twins, you must plan ahead, because excellent parents can give birth to excellent babies.
