Polyploidy is the condition which has more than two sets of chromosomes. If an angiospermic male plant is diploid and female plant is tetraploid, the ploidy level of endosperm will be pentaploid because the female gametes undergoes meiosis and forms gametes (2n). This female gametes (2n + 2n of polar nuclei) fuses with the male gametes (n) .

The ploidy level of the endosperm that will develop after double fertilization in a breeding experiment where the selected male parent is diploid and the female parent is tetraploid will be pentaploid.
Here is the explanation:
Double fertilization is a unique process that occurs in flowering plants, where two sperm cells are involved in fertilizing two different cells within the female reproductive structure. One sperm cell fertilizes the egg cell, forming a diploid zygote which develops into the embryo. The other sperm cell fertilizes the central cell, which is a large cell with two polar nuclei, and this fertilization event gives rise to the endosperm.
In this breeding experiment, the male parent is diploid, meaning it has two sets of chromosomes, while the female parent is tetraploid, meaning it has four sets of chromosomes. During double fertilization, the sperm cell from the diploid male parent fuses with the haploid egg cell from the female parent, resulting in a diploid zygote.
The second sperm cell from the male parent fuses with the two polar nuclei of the central cell, resulting in a triploid (3n) nucleus. The central cell is already tetraploid due to the female parent being tetraploid, and the fusion of the sperm cell and the polar nuclei adds an additional set of chromosomes, making it pentaploid (5n).
Therefore, the ploidy level of the endosperm that will develop after double fertilization in this breeding experiment is pentaploid.
