The female plant contains 36 chromosomes and the male plant contains 20 chromosomes. Calculate the number of chromosomes found in the zygote and endosperm.

Zygote= Male gamete+ Female gamete
PEN= Male gamete + Secondary nucleus. PEN is present inside the PEC which later forms endosperm
Female plant= 36 chromosomes
Gametes= 36/2=18 chromosomes
Male plant= 20 chromosomes
Gametes= 20/2= 10 chromosomes
Zygote= 10+18= 28 chromosomes
Endosperm= Secondary nucleus(2n) +male gamete
Endosperm= 36+10=46 chromosomes
