There are two obvious errors in the answer Impossible, unless you are approximately equal, which is indeed more suitable for the answer Phenotypic plants so p(aa)=aa (aa+aa)=aa (1-aa)=(2 0 02 0 98) ( )= Disclaimer I also have that multiple-choice question at hand, and the answer should be wrong.
-
The answer to the original question is correct. From the aa 4*10 -4 in the question, we can see that p(a)=, p(a)=, and then obtained.
p(aa)=(,p(aa)=2*
The proportion of AA in phenotypically normal individuals was then found.
aa (aa+aa)=aa (1-aa) [2*The probability of albino seedlings in phenotypic normal offspring is:
1/4*(aa)^2=1/4*[2*
So the answer is normal.

The answer is wrong. That's not a small calculation...
Yours is right. I see you know how to be too lazy to say it.
-
a-a 1-a is the frequency of albino genes in phenotypically normal plants, divided by 1- a, which is equivalent to a (1+ a).
Squared, i.e. the answer.
-
We might as well take the square of t as a, which is the albino gene frequency.
Since it is inbred in normal seedlings, it should be noted that all normal seedlings are frequent, so the gene frequency of Baihua is (t-t 2) (1-t 2) = t (1+t), and it is sought by one square.
-
For reference only, because the hybridization of aa and aa should be considered, aa self-inbreeding, the calculation method is p(aa) squared 1 4

This question seems to be a genetic problem, and I'll do the math for you later.

Analysis: Examines the calculation of genotype frequencies. The albino gene is recessive, set to a, its gene frequency is set to q, and the gene frequency of osmosis a is set to p.
The plant population is in equilibrium, so the Harwin equilibrium can be used to solve the problem. The frequency of aa is Q2 = 4 10 4, Q = , P = 1 - Q = . The phenotypic normal plant genotype is AA or, and only the inbred offspring of AA will show albino seedlings.
The genotype frequency of AA in normal plants is 2PQ (P2+2PQ)=2, and the frequency of AA in inbred offspring is 1 4 [2]. The High School Attached to the National People's Congress? )

Albino recessive. aa 1/100 a 1/10
So aa probability.
So aa probability.
The lessons of plants are as follows:1. Thatch and saw. Legend has it that more than 2,000 years ago, Master Luban once went up the mountain to cut down a tree, and unintentionally when Xun Weizhong was cut by a thatch, he felt very strange, why did the tender grass break the calloused hand and bleed? >>>More
The same thing, may both feel wronged, why will everyone be wronged, because everyone's thoughts have their own perspectives, have their own different positions, the fulcrum of this balance is to try to make things in a fair state, try to empathize, sometimes to be humble, family life is like this, because home is not a reasonable place, there is an old saying called "it is difficult for a clean official to decide family affairs" I wish all families can deal with their own crises and live happily.
A bad mood is equivalent to giving yourself poison, first of all, health problems; And people don't like people who have too much negative energy, keeping others away from themselves; If things are not done well, there is no progress in the career or even nothing is achieved, and no money can be made. Because of the bad mood, everything is gone from me, soIt is very important to be in good spirits >>>More
