In sexual reproduction the offspring has similar genetics and look of those of the parents. In asexual reproduction, it will look like the one parent, but it won't have the parent. The parent would have split in two and created two daughter cells, but when they make buds of them they have one child and on parent. Hope I helped! ;)
I believe it’s because they are trying to find other things that won’t pollute the environment as much, and they are also doing this because we are trying to reduce green house gas. Sorry if i’m wrong :(
