Is it a high school student or a college student?
For high school students, a book of Mendelian pea hybridization and Morgan's white-eyed Drosophila hybridization are not enough. This lies in the connection, to find a large number of topics, to be familiar with common genetic models, to form your own genetic system. It is very reflected in the college entrance examination questions, and we should do more in this regard.
For example, the breeding of oil silkworms in the Fujian college entrance examination involves companion genetics. There is also the National Outline Volume, which deals with three pairs of alleles, 3 to the power of 27 and 4 to the power of 256. There are also a lot of incomplete dominant questions, such a relative trait may have many manifestations, the most classic is the color of the emperor penguin fur, light purple, dark purple, blue, white, college entrance examination questions are also involved.
There are also pseudodominant and revertent bodies of fruit flies, etc., as well as recessive homozygous lethality, dominant homozygous lethality, and chain knowledge should also be slightly understood. We must also draw more, draw long, and draw a good genetic pedigree map, and over time, everything will be successfully pushed into the boat. All of them are my genetics reserves.
To build up your own genetics reserves, there are no tricks, only to be well-informed, only to practice a lot, and to understand thoroughly. When encountering various questions, the whole question is clear to the mind. If you are in the third year of high school, the time-consuming genetic questions are often the difference between masters and masters.

Practice is an important part of learning, the proper review method determines the quality of review, directly affects the effect of learning and test results, so how can we do a good job of review?
1. [Consolidate the foundation] The review process is an advanced stage of mastering knowledge, and the quality of review depends on the mastery of basic knowledge. Therefore, when learning new knowledge in ordinary times, we should "work steadily and steadily" and "step by step" according to the normal pace to lay a good foundation. It is necessary to fully understand and master the basic concepts, basic laws, and basic methods.
When learning new knowledge, we must not "swallow dates" and become "raw rice", hoping to make up for it when we review, which will set up obstacles to the comprehensive mastery of knowledge.
What basic concepts, basic laws, etc. have been learned in this unit?
Find out the connections and differences between knowledge points, list the knowledge network, write an outline or draw a diagram;
The key points, difficulties, doubts, points to note, test points and hot spots of the knowledge in this unit;
how well the experiments in this unit are mastered;
What else is not or is not well grasped in this unit?
3. [Check and fill in the gaps] When reviewing, on the basis of your own induction, you will compare it with the teacher's comprehensive and systematic summary. Find out the omissions, analyze the causes, so as to improve your own induction, further strengthen your understanding of knowledge, understand the problems that have not yet been clarified, and thoroughly understand and master all the basic knowledge. Through the above second and third links, the main thing is to link the scattered, individual, and isolated knowledge learned before and turn it into systematic knowledge, so as to make a qualitative leap in the understanding and mastery of knowledge.
4. [Speculation on Example Questions] The example questions in the textbook and explained by the teacher are generally typical and representative. It is necessary to study carefully, deeply understand, and learn to analyze and solve problems through logical thinking and flexible use of the knowledge learned through the "model", especially to learn the ideas for analyzing problems and methods for solving problems, and be able to summarize the laws of problem solving. In this way, we can draw inferences from one case and bypass others.
5. Intensive practice questions] Do not engage in "sea of questions tactics" during review, but should choose a high-quality reference book under the guidance of the teacher, improve your thinking ability and problem-solving skills through problem solving, and deepen your in-depth understanding of what you have learned. When solving problems, we should think independently, think more than one question, solve multiple problems, play with it repeatedly, and realize the truth. Be good at discovering your own shortcomings in problem solving, and find out the root cause and enrich it; It is necessary to be good at summarizing the rules of problem solving in problem solving and improve the ability to solve problems.
In this way, we can use one as ten, and win more with less. Sixth, for the follow-up test after review, the purpose is to check the review effect and cultivate the test-taking ability of students, so it should be taken seriously. On the basis of the teacher's analysis of the test papers, the teacher will conduct a self-summary, mainly summarize the thinking methods and learning methods, find out the problems and deficiencies in learning, and clarify the direction of future efforts.
In short, for the exam, you can't sharpen the gun on the spot, and you should pay attention to the usual.

Recently, the news that triplets and sisters have achieved good results in the college entrance examination has attracted a lot of attention and caused related discussions. ......Whether there is a relationship between a child's academic performance and genes requires a comprehensive analysis of the relevant situation. Specifically, it includes three aspects: innate factors have a very important impact on children's academic performance, acquired efforts are equally important to children's academic performance, and hard work to learn and exert their strengths in order to truly achieve ideal results.
1. Innate factors have a very important impact on children's academic performance.
For a child, innate factors have a very important impact on their academic performance. ......Some children are born very intelligent, have a good memory, and have strong comprehension skills, and these children will definitely do better in their studies under the same conditions. Genes are one of the most important innate factors, so they must have a great relationship with children's academic performance.
2. Acquired effort is equally important for a child's academic performance.
Although the innate factors have a great impact on the academic performance of the children, the acquired factors are equally important. ......Specifically, in real life, only those children who are really able to study hard can achieve good grades, and those who are congenitally good, but do not study hard, cannot be sure of good grades. This is the best proof that acquired factors have a significant impact on a child's grades.
3. Study hard and give full play to your own strengths in order to truly achieve ideal results.
For a child to achieve good academic performance, many conditions must be met. ......Broadly speaking, these conditions fall into two aspects. One is that the child must have good congenital conditions and have good genes.
The second is that the child must have a good attitude of studying hard and be able to study hard. Only when these two conditions are combined can you get good grades and succeed in your studies.
If not a problem. It's just that I think the concept and understanding are more important. Due to the number of words, it is a little troublesome to write. So I still don't write it.
b, be imaginative and imagine yourself standing in that place. It's actually very easy to eliminate them one by one, you just need to remember the degree of the dividing line between the east, west, north and south hemispheres, and then imagine it slowly.
I'm a high school biology teacher, so let's talk about biology. When your mind breaks down, it means that you are not interested in learning. >>>More
There are 6 types. yyrr,yyrr,yyrr,yyrr,yyrr,yyrr.
We only study one pair of alleles at a time. >>>More
This is a classic question.
Two pairs of alleles are involved, a and a (on a pair of autosomes), b and b (on sex chromosomes). >>>More
