Solution

The correct option is C 1
During meiosis taking place for gamete formation, centromeres split and chromatids separate. Hence, each daughter cell receives a haploid number of centromeres. During pollen formation, four haploid pollen granules are produced by meiosis.
As pea plant has a haploid number of 7, all four pollen granules produced by meiosis contain all seven centromeres.
So, the correct answer is '1'.
