Question: what is ploidy of cells of tetrad?
Answer: Microspore tetrad cells are the microspores arranged in a group of four. Microspores are formed from microspore mother cell (MMC). MMC is a diploid cell which undergoes meiosis to form four haploid microspores which are arranged in a tetrad. ... Hence, ploidy of microspore tetrad cells is haploid.
