A diploid male angiospermic plant is crossed with tetraploid female plant. Endosperm of seed will be

Correct Answer: Pentaploid
A diploid male angiospermic plant is crossed with tetraploid female plant. Endosperm of seed will be Pentaploid.
The endosperm is a tissue produced inside the seeds of most flowering plants following the fertilization of male and female gametes. If 2n male is crossed with 4n female, then endosperm will be 5n as female gamete after meiosis form 2n gametes + n male gamete + 2n polar nuclei, therefore 5n ploidy for endosperm.
The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.

Consider the following statements regarding Xenia and choose the correct answer:
1. If a white variety (yy) is pollinated with pollen from a yellow variety (YY), one of the male gametes (Y) will unite with the egg (y) to produce a hybrid embryo (Yy) which will act as a heterozygote for yellow endosperm in the next generation
2. The second male gamete (Y) will unite with the two polar nuclei (y, y) and produces the primary endosperm nucleus (Yyy) which is triploid
3. If a yellow endosperm variety (YY) is crossed with pollen from a white grained variety, the grains produced are white like the pollen parent

If a female plant of genetic constitution AABB is crossed to a male plant of genetic constitution aabb and the F1 is test crossed, the genetic constitution of the test crossed progenies will be
