Answer:
Chromosomes within a cell are arranged in sets. Each cell contains 46 chromosomes or 23 sets.
Such sets of chromosomes are classified according to an international nomenclature: from the largest to the smallest, followed by sex-chromosomes.
Explanation:
A woman has two X sex-chromosomes and a man has one X sex-chromosome and one Y sex-chromosome.
other words, it is just ONE SIMPLE CHROMOSOME what makes us SO DIFFERENT from each other.
Always remember that chromosomes are the same in all human races.
Given that the number of chromosomes for everything to run smoothly should always be kept constant from generation to generation, each individual should only inherit 23 chromosomes from each progenitor at the time of conception. Thus, if a woman has 46 chromosomes and a man has 46 chromosomes, each one has to transmit to their unborn child half of that amount (23 chromosomes) at the time of fertilisation. And so the unborn child will receive 46 chromosomes, 23 from its female parent and 23 from its male parent = 46 in total.
