Question

what is the meaning of this sentence --




(class 12 th chapter -- principles of inheritance and variation )




--> the male honeybees produce sperms by mitosis but they do not have father and thus cannot have sons , but have a grandfather and can have grandsons ?​

Answer 1

Dear, friends :)

Yes ! A male honey bee has no father and cannot have sons, but he has a grandfather and can have grandsons. It is the peculiarity of the haplo diploid sex-determination system.

This phenomenon is known as Haplodiploidy

In this system,the males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid.

So, the male honeybee was created from an unfertilized egg of the queen bee, so it has a mother only and no father.

However sperm was used to create its mother, so the male honeybee has a grandfather.

And if the male honeybee's sperm is used to create the next queen, then the unfertilized eggs that she lays will become his grandsons.

Hope you understand it now!!:))
