[There is a certain degree of fraud in the introduction, everything is subject to the actual product]
Freshman students from nine schools had finished their last final exam and were about to pack their schoolbags and go home, when they were pulled into the infinite world by a mysterious force.
I didn't say I couldn't take a vacation, and I said I had to take the final exam again.
Student:…
RNM, have a holiday!
Unlike other students, Xu Taiwen inexplicably became a BOSS-level NPC in the infinite world - the president of the Ninth School Student Union.
Internally, she is a transit point, an NPC that appears between students to deliver information and manage order. Rather than being regarded as a ferocious beast by the students, it is better to say that they are treated like cattle and horses, running wildly.
Because there are no teachers, the test papers are submitted by students, and the final reviewer is Xu Taiwen, the chairman of the student union.
After all, she endured everything.
Question: The inheritance of the family genetic disease of the student union president of a certain school involves two pairs of alleles on non-homologous chromosomes. It is known that the genotype of his grandmother is AAbb, and the offspring of his mother and uncle will not be affected by the disease. According to the following pedigree chart, the correct inference is:
A. The method of backcrossing can be used to determine whether the inheritance mode of the genetic disease is sex-linked inheritance...
Seeing this, Xu Taiwen, who was reviewing the question, fell silent.
Okay, no need to read any more, this question did not pass the review.

Ding Ding Ding Deng - the following is a collection of outstanding exam moments from outstanding students (written for fun, the text may not appear hehe)
In the first photo, an embarrassed young man covered in mud holds a pot of plants in his hands, with a farmer's harvest joy on his face. Look carefully at the strange-looking plant, with its thin stem, large nozzle, and eyes, which look vivid and twisted into afterimages.
[The top score in the biology subject of the XX Ninth School Joint Entrance Examination, the birth of new varieties of mutant peas may make up for the market shortcomings]
In the second photo, a ferocious-looking girl in overalls was holding a bucket of loaches and pouring them into the toilet. The whole photo has a delicate composition and a very oppressive feel, as if the camera is installed in the toilet.
[The technical subject score of the XX Ninth School Joint Entrance Examination ranks first, and the ecological model of refined sewer loach breeding breaks through the scope of a single subject]
The third photo shows a big explosion. In the light of the fire, a grinning girl slapped a piece of draft paper on the camera. The content on the draft paper is very clear:
Topic: Find the derivative somewhere on this mountain (cross out)
Solution: Obviously, the curve of the side profile of this mountain is a quadratic function (crossed out)
Let f(x)=ax**2+bx+c (cross out)
f'(x)=2ax+b(cross out)
I am your mother (cross out)
All the above are invalid.
Solution: Apparently, the mountain was blown flat.
F'(x1)=0
