Hope it helps you!!
Explanation:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Answer:Before meiosis, the chromosomes in the nucleus of the cell replicate to produce double the amount of chromosomal material. After chromosomal replication, chromosomes separate into sister chromatids. This is known as interphase, and can be further broken down into two phases in the meiotic cycle: Growth (G), and Synthesis (S). During the G phase proteins and enzymes necessary for growth are synthesized, while during the S phase chromosomal material is doubled
.Difference between Meiosis I and Meiosis II Meiosis I Meiosis II
- Starts as diploid; ends as haploid
- Reductive division
- Homologous chromosome pairs separate
- Crossing over happens
- Complicated division process
- Long duration
- Ends with 2 daughter cells
Meiosis II
- Starts as haploid; ends as haploid
- Equational division
- Sister chromatids separate
- Crossing over does not happen
- Simple division process
- Short duration
- Ends with 4 daughter cells
