if an organism produces gametes (haploid) cells that contain 30 chromosomes, how many chromosomes would its somatic cells contain?
90
60
30
15

Explanation:

Step1: Recall cell - chromosome relationship

Gametes are haploid cells. Somatic cells are diploid. Diploid cells have twice the number of chromosomes as haploid cells.

Step2: Calculate number of somatic - cell chromosomes

If haploid gametes have 30 chromosomes, then somatic cells (diploid) have $2\times30 = 60$ chromosomes.

Answer:

60 (corresponding to the second option in the multiple - choice list)
