What is a diploid cell characterized by?

• A. One set of chromosomes
• B. Two sets of chromosomes
• C. Four sets of chromosomes
• D. No sets of chromosomes

Answer: (B)

A diploid cell is characterized by having two sets of chromosomes. This means that for each type of chromosome present in the organism, there are two copies: one inherited from the mother and one from the father. In humans, for instance, the diploid number is 46, consisting of 23 pairs of chromosomes. This arrangement allows for genetic diversity through sexual reproduction, as offspring receive a mixture of genetic material from both parents. The concept of diploidy is crucial in genetics and helps to explain processes such as meiosis, where diploid cells undergo division to produce haploid gametes, which then combine during fertilization to restore the diploid state in the resulting zygote.
