True or False: Both Sperm produced within a pollen grain are genetically unique.?

I'm gonna have to say false.





Each pollen grain will be genetically unique, however, the nuclei within a single pollen grain are genetically identical. Think of pollen production being similar to spermatogenesis, but then add some post-meiotic events. This means that you'll get 4 genetically unique cells at the end of meiosis. Each cell will develop into a pollen grain. Development into a pollen grain requires the cell to produce more nuclei. Each cell will undergo karyokinesis which is a type of endomitosis. Since this is mitosis, the nuclei produced are the same as the nuclei initially in the cell. Each cell produces an additional nuclei and a tube nuclei in typical angiosperms. This means that the genetic makeup of the nuclei in a single pollen grain are identical. So the answer is false.True or False: Both Sperm produced within a pollen grain are genetically unique.?
very true
