WebA diploid cell in G1 has 6 chromosomes. How many chromosomes and how many chromatids are present in each of the following stages? Here is what I am guessing. G1: 6 chromosomes ; 6 chromatids . G2: 6 chromosomes ; 12 chromatids . Prophase: 6 chromosomes; 12 chromatids . Metaphase: 6 chromosomes; 12 chromatids . Anaphase: … WebIn onion root tip, each somatic cell contains 8 chromosomes. A cell undergoing cell division has duplicated its chromosomes thus a cell at metaphase stage of cell division has 16 chromosomes. As each chromosome has two kinetochores thus during metaphase 32 kinetochores can be seen. So, the correct answer is '32'. Was this answer helpful? 0 0
