Like does the more chromosomes in a flower mean it is more advanced.

Ex. Flower A has 12 chromosomes. Flower B has 18 chromosomes. Flower C has 24 chromosomes. Is C more advanced than the others or is B or A.

not necessarily...gorillas have 48 chromosomes...more than us!! AS do many other animals.
Plants are a bit different in that they tolerate changes to chromsomes and chromsome numbers better than animals eg. THere are some fern species that have HUNDREDS of chromosomes...this is a result of polyploidy, where entire sets of chromosomes have been "added" (humans barely tolerate 1 extra chromsome and only on certain chromosomes eg trisomy at chromosome 21 or kelinflelter syndrome XXY) .
So Ferns, which are considered to have primative features, have the highest numbers of chromsomes.....
Also it depends on what characters are on the chromsomes, so technically its the genes and gene combinations that are more important to "advancement" than chromosome number.

I don't think it has to do with advancement
Flowers can only cross pollinate other flowers with the same number of chromosomes or their won't be any new flowers
Kind of like why most animals can't cross breed and if they do their offspring will be sterile
good luck

There is no relationship between number of chromosomes and complexity or advancement of the species. There are species of ferns that have far, far more chromosomes than people have. That does not mean that the ferns are more advanced.

Resultant daughter cells made from mitosis consequence in daughter cells with the comparable sort of chromosomes because of the fact the ascertain. they're going to the two be diploid. despite if, for the period of meiosis, the resultant gamete is haploid. It has 0.5 the kind of chromosomes of the ascertain cellular.
