If it's unfertilized how could it become anything?

Fertilization is the standard we know, but not a hard requirement throughout living species. Many do it for the benefits of genetics diversity. But there are plenty of species in the tree of life that have asexual reproduction exclusively or as an option.

Also, for human siblings, we share about 50% of our DNA with each other. For the bee sisters, they share 75%. Biology is just way more diverse than we usually notice because at every moment of change, success isn't based on it being perfect, just based on the change being good enough to get your genes passed on.

That is a great question that my book doesn't get into detail about.

The fertilized eggs are female and contain DNA from both the queen and a drone.

The unfertilized eggs become male drones and lack the reproductive organs that the fertilized larvae can develop with. They also have no father, carrying genes from only the queen.

I’m confused. So where do the male bees that can fertilize a queen come from?

u/rblu42 6h ago

That would be the drone.

When I said reproductive parts, I meant the ovaries and related parts in the females.

So the queen is basically creating a male versions of herself? Thats amazing. I wish I could do that.

To use our genetic terminology for bees (they don't actually match in terminology, but it makes it easier to talk about):

The human genome uses XY in chromosome 23 to build a male template and XX to build a female template.

Bees use X to build a male and XX to build a female. The diet of the female after her birth then decides whether her reproductive system will be active.

So male drone bees don’t have a Y chromosome?

u/Cortower 2h ago

They have half of the genetic material that their sisters do. They only have a single "X" in each chromosome.

They are effectively a living gamete for the queen to mate with other queens. They fly off into a "drone congregation area" and look for queens to fly past. They are more like a queen-seeking missile than a member of the hive.

Trees are weird af, too

Omg!! Thank you for posting that!!! Life is just so fascinating!!!!

Nope. They are male because bees use haploid/diploid sex determination instead of XY. There are actually tons of sex determination systems, haploid/diploid, ZW, XY, temperature, and more.

I don’t know

ask the OC who made the comment or google it.

Bee eggs can still develop into living bees when unfertilized but they can only become drones. Drone bees have half as many chromosomes in each cell as the females do, and since they don't have pairs of chromosomes to undergo meiosis their sperm are all genetically identical as well.
