What Happens If You Fuse All Your Chromosomes? | SciShow News

The video explores the concept of chromosomes, focusing on a recent experiment where scientists fused yeast chromosomes, reducing their number from 16 to one or two. Despite the drastic change, the yeast functioned normally, with minimal gene expression changes. However, the modified yeast showed reproductive and fitness deficits, suggesting that having more chromosomes might offer evolutionary advantages. The study highlights the potential flexibility in chromosome numbers and its implications for evolution.

How did the chromosome structure changes affect gene expression in the modified yeast?

What evolutionary advantages might come from having a larger number of smaller chromosomes?
