How is triploid PEN (Primary Endosperm Nucleus) is formed? What is indicated by triploid condition of endosperm?
Share
The zygote is produced by the process of syngamy and
the other male gamete fuses with the secondary nucleus
to form the triploid Primary Endosperm Nucleus (PEN).
In angiosperms, the astrological nature of the endosperm
is triploid (3n). In the triploid condition, each nucleus has
three sets of chromosomes.
