Why is polyploidy lethal for some organisms while for others is not?

Polyploidy is like having extra sets of building blocks, it can help some creatures grow strong, but make others feel confused and weak.

Imagine you're playing with lego blocks. Normally, you use one set to build a tower. But if you suddenly get two complete sets, you might not know which block goes where, your tower could end up wobbly or even fall apart!

In some animals and plants, like humans, having extra sets of genes (that’s what polyploidy means) can cause problems during development. It's like trying to build a house with too many instructions all at once, everything gets mixed up, and the result might not be healthy.

But in other creatures, like some kinds of wheat, having extra sets of genes is fine, even helpful! They use those extra genes to grow bigger or survive better. It’s like having more lego blocks, you can build taller towers or stronger structures.

So whether polyploidy is good or bad depends on the creature and how it uses its extra sets of building blocks. Polyploidy is like having extra sets of building blocks, it can help some creatures grow strong, but make others feel confused and weak.
