if one can have two, it will save! The discussion of twins after the opening of the two children More and more. Born on the same month of the same year, it also looks like the biggest interest in twins. However, a recent news made people more interested: a British couple had a pair of identical twin sisters, and two girls were white and black, the first difference in the complexion of identical twins in the UK.
this pair of British twins, the mother is the white, the father is the black, so the sisters are black and white, and this occurs in only one millionth of the identical twins.
in my Ji'nan, some twins are different, such as the 5 year old coincidence and Beckham, which is a mother, a father, a double eyelid, and a single eyelid.
twins share the same eggs and double eggs. Ding Feng, deputy director of Obstetrics and Gynecology of the 456 Hospital of the PLA, said. In general, identical twins are very similar. Twins with twins have a mother like father.
from the clinical point of view, most of the same sex twins are mostly identical, and their skin color and appearance are similar. However, this is not a certain situation, in the same sex twins, there will be twin twins, such as the previous said Qiao and Beck, although the two girls, but also different.
the twins must be twins. Usually the genes of dragons and foetuses are composed of different X\Y supplied by parents, so there are not many similar twins.
Fan Xiufang said that identical twins generally have the same appearance, stature and height, but their personality may be completely different. In addition, the fingerprints and DNA of identical twins are different.
twins are actually two separate fertilized eggs, relatively low in similarity. Fan Xiufang said.
data show that twins have a certain heritability, but the probability of birth is very low. If the mother is twins, the probability of twins in the next generation is 1.7%, and if the father is twins, the probability is lower.
however, from the current situation in Ji'nan, twins are more likely to be born than before. In recent years, obstetricians in major hospitals in Ji'nan have similar feelings. The birth rate of twins has been greatly improved. Obstetric experts analysis, this is mainly related to the application of ovulation drugs and the development of assisted reproductive technology.
