Question 1 Report

The chromosome number of a cell before and after the process of meiosis is conventionally represented as

2n → 2n

n → n

n → 2n

2n → n

Answer Details

The chromosome number of a cell before and after the process of meiosis is conventionally represented as "2n → n". This means that the cell starts with a diploid number of chromosomes (2n), which is reduced by half through the process of meiosis, resulting in haploid daughter cells with half the number of chromosomes as the parent cell. So, "2n → n" represents the reduction in chromosome number from diploid to haploid during meiosis.
