    If an angiospermic male plant is diploid and female plant tetraploid, the ploidy level of endosperm will be

    A) haploid          

    B)        triploid

    C) tetraploid          

    D)        pentaploid

    Correct Answer: D

    Solution :

    [d] The male gamete will be haploid (n). 2 polar nuclei will be diploid (2n). Endosperm formed by fusion of male gamete with two polar nuclei will be pentaploid. \[\underset{(n)(2n)+(2n)(5n)}{\mathop{\text{male gamete }+\text{ }2\text{ polar nuclei }\to \text{ Endosperm}}}\,\]
