1、There are still some fathers and mothers who only like sons and only want boys. This is unscientific and violates the laws of nature. If you can choose the gender of the baby according to the wishes of these parents, resulting in a significant imbalance between the gender ratio in society, it will have a very negative factor for social stability. Xiao Bian summed up the knowledge about genetic factors affecting boys and girls for your reference.
還有一些父親和母親只喜歡兒子，只想要男孩。這是不科學(xué)的，違反了自然法則。如果你可以根據(jù)這些父母的意愿選擇嬰兒的性別，導(dǎo)致社會性別比例之間存在顯著的不平衡，那將對社會穩(wěn)定產(chǎn)生非常不利的影響。小編總結(jié)了影響男孩和女孩的遺傳因素的知識，供大家參考。
2、 Genetic factors affect gender
遺傳因素影響性別
3、 Regardless of which country, nation or ethnicity in the world, the proportion of male and female sex is objectively quite regular. The so-called gender ratio means that the ratio of men and women in the natural population is It is expressed as the number of males when the female is 100. According to the 1987 national 1% population sample survey, the sex ratio is 104.5. Men accounted for 51.1% and women accounted for 48.9%. The sex ratio at each stage of life is most interesting in terms of sex ratio at birth. According to research, genetic factors can affect the sex ratio. If the mother's blood type is AB type, there are more opportunities for boys than for girls; some families have more boys, while others have more girls. The impact of race is even more pronounced. For example, in African Americans, the sex of newborns is relatively low, below 104, while in some countries in the Far East, the gender is relatively high, according to South Korea's report of 115.
無論世界上哪個國家，國家或種族，男女性別的比例客觀上都是非常規(guī)律的。所謂的性別比例意味著自然人口中男性和女性的比例是表示為女性為100時的男性人數(shù)。根據(jù)1987年全國1％的人口抽樣調(diào)查，性別比例是104.5。男性占51.1％，女性占48.9％。在出生性別比方面，每個生命階段的性別比最為有趣。根據(jù)研究，遺傳因素可以影響性別比例。如果母親的血型是AB型，那么男孩的機(jī)會多于女孩; 一些家庭有更多男孩，而另一些家庭有更多女孩。種族的影響更加明顯。例如，根據(jù)韓國115的報告，在非洲裔美國人中，新生兒的性別相對較低，低于104，而在遠(yuǎn)東的一些國家，性別相對較高。
4、 The birth of a boy is determined by the sperm. Sperm is divided into two types of chromosomes, 23X and 23Y. The former fertilization develops into a female fetus, and the latter develops into a male fetus. The ratio of their birth is 1:1, so the natural probability of male to female ratio should also be 1: 1. However, since the sperm and endurance of the sperm with X and Y chromosomes are significantly different, the tolerance and survival time of external factors are also different, so the fertilization ability of the two spermatozoa is different under different conditions.
一個男孩的出生是由精子決定。精子分為兩種類型的染色體，23X和23Y。前者受精發(fā)育成女性胎兒，后者發(fā)育成男性胎兒。他們的出生比例是1：1，因此男女比例的自然概率也應(yīng)該是1：1。但是，由于精子與X染色體和Y染色體的精子耐力顯著不同，因此耐受性和存活時間外部因素也不同，因此兩種精子的受精能力在不同條件下是不同的。
5、 Under normal circumstances, the sperm with Y chromosome has excellent motility, but the endurance is poor, and it is relatively vulnerable to external adverse factors. The survival time is not long. In the same room as the ovulation day of the expectant mother, the male baby is likely to be large. The sex of the sperm with X chromosome is poor, the endurance to the bad environment is good, and the time to survive and maintain the insemination ability is longer. Therefore, in the same room several days before ovulation, the female fetus is likely to be large. Spleen with X chromosome prefers an acidic environment, while sperm with Y chromosome prefers an alkaline environment. Therefore, adjusting dietary habits, eating more vegetable foods, and washing the vagina with a weak alkaline solution can increase the probability of giving birth to a male child. Conversely, eating more meat is prone to girls.
在正常情況下，具有Y染色體的精子具有極好的運動性，但耐力性差，并且相對易受外部不利因素的影響。生存時間不長。在與準(zhǔn)媽媽的排卵日相同的房間里，男嬰可能很大。X染色體的精子性別差，對惡劣環(huán)境的耐受性好，生存和維持授精能力的時間更長。因此，在排卵前幾天的同一房間，女性胎兒可能很大。有X染色體的脾臟喜歡酸性環(huán)境，而有Y染色體的精子喜歡堿性環(huán)境。因此，調(diào)整飲食習(xí)慣，多吃植物性食物，以及用弱堿性溶液沖洗陰道會增加生育男孩的可能性。相反，多吃肉類容易產(chǎn)生女孩。
6、 Drug operation can be selected. For example, after the artificial ovulation induction of clomiphene citrate, the sex ratio of the baby is significantly higher than that of the male baby. Also, expectant mothers who are prolific and prolific, have fewer chances to have a baby than a raw girl. But after 45 years of age, the sex ratio of newborn babies can rise to 120-130. Smoking can reduce the sex ratio to below 100. There are still a few parents, patriarchal, and only boys, which is against the laws of nature. If the gender of the fetus can be chosen according to the wishes of these people, resulting in a significant imbalance between the gender ratio in society, there will be factors that are extremely detrimental to social stability.
可以選擇藥物操作。例如，在人工排卵誘導(dǎo)克羅米芬檸檬酸鹽后，嬰兒的性別比例顯著高于男嬰。此外，多產(chǎn)和多產(chǎn)的準(zhǔn)媽媽生孩子的機(jī)會少于生女孩。但是在45歲之后，新生兒的性別比例可以上升到120-130。吸煙可以將性別比降低到100以下。仍然有一些父母，父權(quán)制，只有男孩，這違反了自然規(guī)律。如果可以根據(jù)這些人的意愿選擇胎兒的性別，導(dǎo)致社會性別比例之間存在顯著的不平衡，那么就會有一些對社會穩(wěn)定極為不利的因素。
7、 Summary: There are many knowledge about genetic factors affecting boys and girls, such as: the birth of a boy is determined by the sperm. Therefore, in different situations, the fertilization ability of the two sperm is different. After clomiphene is artificially ovulated, the female baby is significantly more than the male baby.
摘要：關(guān)于影響男孩和女孩的遺傳因素有很多知識，例如：男孩的出生是由精子決定的。因此，在不同的情況下，兩種精子的受精能力是不同的?？肆_米芬人工排卵后，女嬰明顯多于男嬰。
