Vedclass · Answer

(D) In angiosperms,the endosperm is formed by the process of double fertilization,specifically through the fusion of one male gamete $(n)$ with two polar nuclei ($n+n$ or $2n$ depending on the female parent's ploidy).Given that the male plant is diploid $(2n)$,its gametes are haploid $(n)$.Given that the female plant is tetraploid $(4n)$,its embryo sac is formed from a megaspore mother cell $(4n)$ via meiosis,resulting in haploid megaspores $(2n)$.Thus,the polar nuclei in the central cell of the embryo sac will each be diploid $(2n)$.The endosperm is formed by the fusion of one male gamete $(n)$ and two polar nuclei $(2n + 2n)$.Therefore,the ploidy of the endosperm is $n + 2n + 2n = 5n$,which is Pentaploid.

If an angiospermic male plant is diploid $(2n)$ and the female plant is tetraploid $(4n)$,what will be the ploidy level of the endosperm?
