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.
还有一些父亲和母亲只喜欢儿子，只想要男孩。这是不科学的，违反了自然法则。如果你可以根据这些父母的意愿选择婴儿的性别，导致社会性别比例之间存在显着的不平衡，那将对社会稳定产生非常不利的影响。小编总结了影响男孩和女孩的遗传因素的知识，供大家参考。
2、 Genetic factors affect gender
遗传因素影响性别
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.
无论世界上哪个国家，国家或种族，男女性别的比例客观上都是非常规律的。所谓的性别比例意味着自然人口中男性和女性的比例是表示为女性为100时的男性人数。根据1987年全国1％的人口抽样调查，性别比例是104.5。男性占51.1％，女性占48.9％。在出生性别比方面，每个生命阶段的性别比最为有趣。根据研究，遗传因素可以影响性别比例。如果母亲的血型是AB型，那么男孩的机会多于女孩; 一些家庭有更多男孩，而另一些家庭有更多女孩。种族的影响更加明显。例如，根据韩国115的报告，在非洲裔美国人中，新生儿的性别相对较低，低于104，而在远东的一些国家，性别相对较高。
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.
一个男孩的出生是由精子决定。精子分为两种类型的染色体，23X和23Y。前者受精发育成女性胎儿，后者发育成男性胎儿。他们的出生比例是1：1，因此男女比例的自然概率也应该是1：1。但是，由于精子与X染色体和Y染色体的精子耐力显着不同，因此耐受性和存活时间外部因素也不同，因此两种精子的受精能力在不同条件下是不同的。
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.
在正常情况下，具有Y染色体的精子具有极好的运动性，但耐力性差，并且相对易受外部不利因素的影响。生存时间不长。在与准妈妈的排卵日相同的房间里，男婴可能很大。X染色体的精子性别差，对恶劣环境的耐受性好，生存和维持授精能力的时间更长。因此，在排卵前几天的同一房间，女性胎儿可能很大。有X染色体的脾脏喜欢酸性环境，而有Y染色体的精子喜欢碱性环境。因此，调整饮食习惯，多吃植物性食物，以及用弱碱性溶液冲洗阴道会增加生育男孩的可能性。相反，多吃肉类容易产生女孩。
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.
可以选择药物操作。例如，在人工排卵诱导克罗米芬柠檬酸盐后，婴儿的性别比例显着高于男婴。此外，多产和多产的准妈妈生孩子的机会少于生女孩。但是在45岁之后，新生儿的性别比例可以上升到120-130。吸烟可以将性别比降低到100以下。仍然有一些父母，父权制，只有男孩，这违反了自然规律。如果可以根据这些人的意愿选择胎儿的性别，导致社会性别比例之间存在显着的不平衡，那么就会有一些对社会稳定极为不利的因素。
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：关于影响男孩和女孩的遗传因素有很多知识，例如：男孩的出生是由精子决定的。因此，在不同的情况下，两种精子的受精能力是不同的。克罗米芬人工排卵后，女婴明显多于男婴。
8、 After the artificial ovulation of fen, the female baby is obviously more than the male baby and so on.
人工排卵后，女婴明显多于男婴等。
9、 After the artificial ovulation of fen, the female baby is obviously more than the male baby and so on.
人工排卵后，女婴明显多于男婴等。
