why are bananas yellow

Because that’s just what color they are. Why are tomatoes red? Why are limes green? Who knows?

because of “so” !

the pigments in the skin of a ripe banana happen to be yellow. I’m sure natural selection has had a lot to do with this.

Many fruits actually co-evolved with the birds and mammals that eat them (and therefore spread their seeds). Certain animals are attracted to fruits of a particular color. If a fruit does a good job of attracting a pollinator or seed disperser, there is a greater chance that that particular fruit tree will successfully germinate and have more offspring (greater reproductive success). As it turns out, most primates that eat fruit are attracted to fruits in trees like figs, and not so much bananas. Banana “trees” are not really trees. If you’ve ever seen a banana “tree” you can see why it wouldn’t be able to accommodate a group of monkeys. This doesn’t mean primates don’t love bananas (they do).

So to answer your question, I don’t know why bananas are yellow. But I’m guessing it has to do with who eats it and helps to germinate it.

ananas are not yellow. Its just because farmers have been cross breeding bananas for so long that their unnatural color is yellow. There are also no seeds for this reason

Yeah, there’s like three seeds per 100 bananas, which is crazy.

It is because of how light reflects off of them
