INTRODUCTION:
As a MOD I've watched this for a long time and finally want to make this post to pin it and decrease the number of people asking this because it keeps increasing.
WHAT IS IT?:
White avocados as seen on these pictures that I just grabbed from other reddit posts, have a form of albinism.
Usually plant leafs are mostly green because it is the "color of chlorophyll" or if I remember correctly from Biology class a few years ago, the only color that isn't absorbed by it to make photosynthesis and thus it reflects and looks green.
The reason that these leafs are white are thus because they do not contain any chlorophyll.
WHAT DOES THAT MEAN FOR THE PLANT?:
If leafs don't contain any chlorophyll it means there can't be photosynthesis which means the plant cannot produce energy on itself.
For an avocado that isn't too bad in the beginning because it still has its seed which has energy reservoirs, but they will be exhausted at some point.
For its survival the avocado thus needs to reach a turnaround point and produce green leafs containing chlorophyll later which happens to some but not all so it's a wait and see.
WHY DOES THIS HAPPEN?:
This is not clear but there has been research about it: Research of Albinism in Avocados
If I remember correctly the research itself or another source I found, comes to the conclusion that this happens increasingly because Avocados are often picked very early to still be ripe or before ripe despite long travelling times, when they arrive in their destination country after export/import.
END:
I hope this helps clear up things and decreases the number of posts regarding this at least a little.
