Verified step by step guidance

Understand the basic definitions: Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Meiosis, on the other hand, is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.
Identify the key processes involved in mitosis: Mitosis involves the replication of chromosomes and their equal distribution into two daughter cells. The main stages include prophase, metaphase, anaphase, and telophase, followed by cytokinesis.
Identify the key processes involved in meiosis: Meiosis includes two rounds of division, meiosis I and meiosis II. Key processes include pairing of homologous chromosomes, crossing over (exchange of genetic material between homologous chromosomes), and reduction of chromosome number by half.
Compare the processes: Crossing over and pairing of homologous chromosomes are unique to meiosis and occur during prophase I. Reduction of chromosome number by half is also a characteristic of meiosis.
Determine the unique process: Formation of two identical daughter cells is unique to mitosis, as meiosis results in four genetically distinct haploid cells. This is the process that distinguishes mitosis from meiosis.
