Assignment from my biology teacher on karyotypes

AI Thread Summary
The discussion revolves around a biology assignment focused on karyotypes, where the user has encountered an issue with an extra large chromosome in their karyotype analysis. To determine the sex, it's essential to identify the presence of either XY (male) or XX (female) sex chromosomes. The extra chromosome may indicate a mutation, potentially a trisomy disorder, suggesting an abnormality in chromosome number. The extra large chromosome is likely one of the first chromosomes, as they decrease in size in a typical karyotype. Understanding these aspects is crucial for correctly interpreting the karyotype.

hi everyone. I recently got an assignment from my biology teacher on karyotypes. i am asked to pair up the chromosomes together and state its sex. But at the end i ended up with 23 paired chromosomes and 1 extra big chromosome. Can anyone tell me what is wrong with this karyotpye? Thanks in advance.

Well, you'll be able to state its sex by knowing whether or not your karytope had (X,Y) or (X,X) sex chromosomes.

As for the extra large chromosome, it could be that your karyotype shows a mutation, such as a trisomy disorder. Since you said it was an "extra big chromosome," it must be one of the first, for they decrease in size.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
