3 AnswersMathematics1 year ago### Hi, could someone please help me with a biology question?? This is regarding chromosomal mutations?

The question is:

Two homologous chromosomes meet in the centre of a cell during meiosis-1. However they do not align correctly. Crossing over results in these homologous chromosomes exchanging different amounts of genetic material. Explain how this could cause a duplication or deletion mutation.

I have tried researching it and i have looked at my textbook but i m not really sure how i could put this into words, when I don t understand. So if someone could clarify that would be amazing!!

thanks for the help anyone
