검증된 단계별 안내1
Recall that a diploid cell contains two sets of chromosomes, one set inherited from each parent.
Understand that humans have a total of 46 chromosomes in their diploid cells.
Recognize that these 46 chromosomes are organized into 23 pairs, where each pair consists of homologous chromosomes.
Note that the number 92 chromosomes would correspond to a tetraploid cell (4 sets), which is not typical for human somatic cells.
Conclude that the correct description of a human diploid cell is 46 chromosomes, consisting of 23 pairs.
