What type of structures have the same structure or function, but they do not share a common ancestor such as the wings of an insect and the wings of a bat.

I'm glad you asked!

Explanation:

Since there is no common ancestor ,that makes the structures analogous or  structures that evolved independently in two living organisms to serve the same purpose.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
