I could not solve the 40th question in the past paper of imat which belongs to 2020. If there is anyone who has an explanation for the question which is about the mutations I would appreciate it. I studied mutations but the question confused me b y saying “two different individuals”. How come we compare the order of two different genes/chromosomes? I don’t know how to share the question here but as I have said it is the 40th question from the 2020 paper.

hey, I have tried to copy and paste the image but it seems like there is a problem. But I can attach the link of the paper I am talking about. The question I had a problem with was 40th. https://accessoprogrammato.miur.it/compiti/CompitoInglese2019.pdf

Hello, as you know, the answer is A, so look at P and Q, you’ll see the different base pair starting from 8th base pair (G-A).
– If it is addtion type: in Q, it must be …GGGAT or GGAGT but it is GGAT => deletion type.
– Because it is deletion type, so the nucleotide subsequence after 8th base pair are pushed forward, but you can see that the length of P and Q are the same => there is also addition type.
– Then, you can see in 11th and 13th base of Q are different from P (after …ATT in P is CCCT whilst in Q is GCAT)
+ 11th base of Q is substitution (substition is replaced by a base of the same kind: G, C)
* If 11th base of Q is addtion => it must be GCCT (!!!)
+ 13th base of Q is addtion as we mentioned above, and also there is ONLY ONE addtion type in Q (if there are two => the length of two is not the same)
