Answer :
The chromosome constitutions in a normal diploid Arabidopsis thaliana plant is 2n=10. A scientist applied colchicine to the seedling, the chromosome number of the resultant tetraploid plants is four times of the original.
How many total * chromosomes * are present in a normal diploid Arabidopsis cell?
Arabidopsis thaliana has ten chromosomes in a somatic nucleus, two each of five distinct types.
Like humans, Arabidopsis is diploid, with a diploid number of ten and a haploid number of five.
Thus, the chromosome number of the resultant tetraploid plants is four times of the original.
