Which of the following sets are correctly matched?

• Somatic = Diploid ; Gamete = Haploid
• Somatic = Haploid ; Gamete = Diploid

Which of the following sets are correctly matched?

• Diploid = 2n ; Haploid = n
• Diploid = n ; Haploid = 2n

True or False: It is necessary for gametes to be haploid (have half the number of chromosomes) so that chromosome number is maintained from one generation to the next.

• True
• False

In humans, when is the chromosome number restored to 46?

• Fertilization
