They say siblings share about 50% of their DNA. Yet it is also said that bananas and humans share 50-60% of their genetic material. What exactly is each claim referring to?
In: Biology
Lets say you have two cookbooks with 99% of the same recipes, just slightly different versions in some cases, separated into the same chapters. For each chapter, pick at random which parent book to copy it from. If you do this again, you have two sibling cookbooks with 50% identical chapters.
For a banana analogy, compare one of these cookbooks to another recipe book, this time with only about half the recipes the same, the rest are different, there are more chapters, and the recipes aren’t categorized the same way.
