Inversion of dna sequences within chromosomes is a common process in evolution. the following gene arrangements in a particular chromosome are found in four different species. 1st sequence stuvwx 2nd sequence svwxtu 3rd sequence stxwvu 4th sequence xwvstu assuming that the arrangement in 1 is the original arrangement, in what evolutionary order did the four species arise, such that there is only one inversion between each species. (place sequence 1in first of your ordering.) next to each sequence, select, from the drop down menu, the order in which each inversion arose.

Ответ:
1-->3-->2-->4
Explanation:
If the original arrangement is the one in the first sequence, and between species only one inversion happened, then the evolutionary order can be the following one:
