In an angiosperm a female plant having 2n = 24 is crossed with a male plant having 2n = 12. What will be the chromosome number of the endosperm ? A) 12 B) 18 C) 24 D) 30

Correct option:(D)30

Solution:

  • Female angiosperm plant with 2n = 24 forms haploid egg cells with n=12 and diploid central cell with 2n= 24.
  • Male angiosperm plant with 2n=12 forms haploid male gametes with n=6.
  • Fusion of haploid male gamete (n=6) with diploid central cell (2n=24) will form the endosperm with 3n= 30.
