It is often said that a daughter takes after her father, and a son takes after his mother. In fact, from a biogenetic perspective, genes are a very mysterious thing, but there are some basic rules of genetic inheritance that we can understand in advance
1 .Height: half for each parent, 35% for the father, 35% for the mother, and 30% for the baby.
2. Intelligence: Boys follow their mother, half half of girls follow their parents (genes related to intelligence are mainly on the x chromosome). 
3. Personality: Follows her father (girls are more influenced by their father).
4. Skin color: Neutral color rule (both parents are white/black – the baby is both white/black, one parent is black and the other is white, the baby generally has a neutral skin color).
5. Double eyelids: Dominant inheritance, if one parent has single eyelids and the other has double eyelids, then the baby is most likely to have double eyelids. But both parents have single eyelids, and most children also have single eyelids.
6. Eyelashes, eyes, nose, and ears: Dominant inheritance. If one parent has long eyelashes, big eyes, a straight nose, and big ears, the child is more likely to inherit it.
7. Obesity: If one parent is fat, the baby will have a 40% chance of being obese. If both parents are fat, the baby will have a 60-80% chance of being obese.
8. Baldness: Follow dad, pass it on from male to female. If the father is bald, the probability of the child being bald is 50%; if the grandfather is bald, the probability of the grandson being bald is 25%.
9. Temper: The baby’s temper is closely related to the mother’s emotions during pregnancy! If the mood is stable, the baby will have a good temper. If the mood is bad, the baby will most likely not have a temper. (During pregnancy, the father should take care of the mother\’s emotions, so that a good baby will be born)
10. Personality: Like the father, the personality can be Cultivated, in a family, the father\’s personality can affect the development of the child. In the mother\’s belly, the child can better identify the father\’s voice and learn his way of speaking, thus laying the foundation of character
A boy , The birth of a girl is related to the father
A boy is XY, X (egg) comes from the mother, and Y (sperm) comes from the father.
Girls are XX, X (egg) comes from mother, X (sperm) isFrom Dad.
The male’s sperm determines whether the couple will have a son or a daughter
The genetic phenomena mentioned above can explain most cases, but there may also be exceptions or special circumstances, and the influence of living environment and Conditions, etc. will also affect the baby\’s appearance and characteristics. Parents should treat it rationally.
