Two near inbred parental lines P1 and P2 of an angiosperm species are crossed to produce F1 seeds in which, the ploidy of the endosperm is 6N. If plants generated from these F1 seeds are backcrossed with P1 what will be ploidy of the somatic cells in the next generation ?
Endosperm will have two polar nuclei and one male gamete. [3N= 2N +N] It is given in the statement that the ploidy of endosperm is 6N. Hence 6N = 4N + 2N. All gametes will be 2N...
