Final answer:
Diploid cells typically have a longer diploid phase, in which they spend most of their life and carry out mitotic cell reproduction, compared to the shorter haploid phase where haploid gametes are produced via meiosis.
Step-by-step explanation:
Diploid cells typically have a longer diploid phase than haploid phase.Diploid cells have two sets of chromosomes and are denoted as 2n, where 'n' represents the number of sets of chromosomes. In humans and many other organisms with a diplontic life cycle, the diploid phase is the dominant stage during which the organism spends most of its life and carries out mitotic cell reproduction. Only the gametes, which are the sex cells, are haploid (n), and they serve as the vehicle for combining genetic material from two parents.
After the haploid gametes unite during fertilization, a diploid zygote is formed which quickly enters the next cell cycle phase leading to the growth of a diploid organism. For example, humans undergo a diploid life cycle, where meiosis is a reproductive process that produces haploid gametes and ensures genetic diversity.
