Explore genetic 14 large "strange" phenomenon

Question one: do not like a father to not like mother, the child whose baby?

Positive solutions: the child is not like father like MOM, this does not mean that children are not natural. People face, stature and personality and intelligence of such genetic except for several genes control, also under the influence of non-genetic and environmental factors.

Human genetic characteristics there are two main classes: one is decided by a simple pair of allele of genetic characteristics, called a single-gene traits such as blood type, DNA polymorphism, etc. Fathers and mothers to have their genes to future generations, composed children's genotype, once formed, no longer change. The other is a complex genetic characteristics, such as a person's height, weight, colour, such as intelligence, personality, behavior and appearance. These traits are formed after the interaction between genes and environmental conditions. Role of each gene is small, on the interaction of genes determines the characteristics of the individual. When meiosis of sperm, eggs mature, combinations of genes located on different chromosomes are random, so each gene can not be the same between compatriots, looks are not exactly the same. Larger complex genetic characteristics under the influence of environment, such as height and weight, and living conditions, nutritional status, lifestyle and other factors directly related to the day after tomorrow; IQ and education-related.

Question two: "black Li Kui" students "snow"?

Positive solutions: Yes. Human skin color inheritance is controlled by the more than 2 on gene, genes to future generations of different colour effect is the same, there is no difference between recessive, so if the father's colour is black, while his mother fair-skinned, then the child will have a "neutral" color. In the same race marriages, little difference in their off-spring colour, if one white and one black marriages, then gave birth to offspring is a dark gray.

Question three: as a child, short nose, did grow up and have the potential to become a high nose?

May, of course, this is genetic is interesting in the nose. Nose genetic continued into the adult stage. Of course want to have a straight nose, tall, narrow holes, parents must have small nostrils, narrow nose, and at least one nose high straight.

Question four: parents are type a, children can do is O-type?

Positive solutions: Yes. General People's Congress knows the human ABO blood group system has four kinds of blood type o, a, b, AB, in fact, these four phenotypes. Its gene type-00 type, AO, AA type, B0, BB-and AB-6, with type a blood is detected, its genotype AA or AO,B type blood is the same reason. It is for this reason, the so-called a-parents may not be the AA, but AO, then when both parents carry the O when sperm-egg combination of genetic factors, child is the o-type blood. Also, a person's blood type may not be unchanged for life, cancer, blood transfusion, such as medication and receiving radiation treatment, short-term change in blood type would, over time will be reinstated. Those suffering from leukemia, aplastic anemia in children after bone marrow transplant, blood type permanently become identical to the donor. In addition, because human blood group has not yet completely understood, are found in very limited circumstances "goes against the" inheritance of the above.

Question five: dad is black eyes, MOM blue eyes, what is the baby's eye color? Eye color genetic followed "deep relatively light color is colors such as black autosomal" principle.　　　In other words, if you want to give the baby blue eyes, even if you selected the blue eyes of love, because you are a black eye, chances of your baby is born with blue eyes are very small.　　Question six: near, hyperopic eye will do genetic? Myopia in whether the baby will have certain relations with genetic, especially when when parents are high myopia, baby chances of myopia is greater, if not the birth become myopic, and be a myopic carriers of the gene, once under the influence of the environment, the possible development of myopia. However, according to the related display: because the number of genetic factors, become myopic only 5% per cent of the total number of myopia, visible effects of postnatal environment and habits should not be overlooked. In addition, the hyperopia and genetics have a certain relationship.

Question seven: dad was short, baby will do short? "Mother low one, father low Wo", this statement is a misinformation. Height is Polygenic inheritance.　　　And the factors which determine standing 35% from the father, 35% from mother, remaining 30% were concerned with nutrition and exercise.　　Question eight: do less bald genetic? Less baldness is hereditary, and dominant genetic male baby who is, in female babies who are recessive. Broadly speaking, less bald is the father passed on to his son.　　If the father is bald, grandfather is bald, male babies the incidence is probably 100%; if the father is not bald, grandfather less bald, male babies there are 25% possible; if the father is not bald, grandfather head thick hair, that baby bald virtually 0. In addition, a young person with greying hair and genetic has a great relationship. If the father is a young person with greying hair, baby will be very high possibility of a young person with greying hair.

Question nine: mixed skin, like who?　　　People of colour are Polygenic inheritance, different colour genes to future generations is the same, that is, two different colour to marry, mixed colour rendering of MOM and dad colour intermediate.　　Ten questions: do body associated with the genetic? Shape is Polygenic inheritance. According to statistics, MOM and dad are thin, baby-mostly thin, only 7% is fat; one of the parents of obesity, obesity in baby 40%; parents were obese, obesity in baby 80%. Obese people tend to have a family history, But the effects of environmental factors on the body is also very large, living conditions, nutrition, movement after birth, such factors as the nature of the work to shape a role.

Question 11: why some twins like some are not like? Twins can be divided into identical twins and fraternal twins. So-called identical twins means that only a single egg fertilization, eggs after the first split, formation of 2 cells with different development into 2 embryos of identical twins. Due to the 2 fetus comes from the same fertilized egg, genetic material is identical, so gender is the same, their genetic characteristics and performance features almost no difference, the appearance is also similar to the special, this identical twins called twins.　　　On the contrary, fraternal twins were 2 mature egg formation 2 and 2, respectively a sperm fertilizing an egg, their development into a complete embryo twin mode, because the twins from 2 different fertilized eggs, so may not be the same as their gender may and genetic characteristics and the larger difference performance characteristics.　　Question 12: do character genetic? The so-called "has its parent will have its", and baby and MOM and Dad on the character of a similar nature, inheritance. But are also related to the culture of the day after tomorrow. As Pavlov says: "character is a natural and metazoan alloy, character of Yu Zu genetic, in real life and constantly changing, perfect. ”

Question 13: do longevity is genetic? Longevity is Polygenic inheritance, not only involves multiple genes, but also under the influence of diet, exercise, and the environment.　　　Longevity of genetic characteristics with two points: one is the longevity can be multigenerational continuous longevity, or generational longevity, or just two generations of longevity; second, renders the matrilineal genetic advantage, meaning that women live longer than men.　　Question 14: do intelligence associated with the genetic? Facts have shown that intelligence and genetic is a certain relationship. In General, parents of high intelligence, baby's higher intelligence; intelligence General parents, baby's intelligence is also common; parents intellectual deficiencies can also cause the baby's intellectual development.　But the day after tomorrow and nutrition education, learning, and other factors in the development of intelligence also plays a considerable role only a combination of innate and acquired immunodeficiency syndrome, to maximize mining on baby's intelligence.
