What is the difference of prophase and prophase 1?
There are a couple of differences between mitotic prophase and prophase I. During prophase I, homologous chromosomes come together. During prophase I, these homologous chromosomes pair up and sometimes intertwine. A process called crossing over can happen during prophase I.
What is the difference between prophase 1 and prophase 2 in meiosis?
Prophase 1 is the initial phase of meiosis 1 and prophase 2 is the initial phase of meiosis 2. The main difference between prophase 1 and 2 is that genetic recombination occurs through crossing overs and the “Chiasmata” formation during prophase 1 whereas no genetic recombination is noticed at the prophase 2.
What are the differences between mitosis and meiosis?
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
What happens in prophase 1 of meiosis?
During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent. Chromosomal condensation allows these to be viewed in the microscope.
What are three differences between mitosis and meiosis?
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
What is the major difference between prophase and telophase?
is that telophase is (biology) the final stage of mitosis or meiosis during which the daughter chromosomes move towards opposite ends of the nuclear spindle while prophase is the first stage of mitosis, during which chromatin condenses to form the chromosomes.
What is the difference between Telophase 1 and telophase 2?
The key difference between telophase 1 and 2 is that the telophase I is the termination phase of the first nuclear division of meiosis and results in two daughter cells while the telophase II is the termination phase of the second nuclear division of meiosis and results in four daughter cells at the end of the process.
What are 10 differences between mitosis and meiosis?
What Is the Difference Between Mitosis and Meiosis?
| Mitosis | Meiosis | |
|---|---|---|
| Number of cells created | End result: two daughter cells | End result: four daughter cells |
| Ploidy | Creates diploid daughter cells | Creates haploid daughter cells |
| Genetics | Daughter cells are genetically identical | Daughter cells are genetically different |
What is the major difference between mitosis and meiosis 1 in a diploid organism?
What is a major difference between mitosis and meiosis I in a diploid organism? Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I.
What happens in prophase 1 of mitosis?
What happens during prophase 1 of meiosis that does not happen during prophase 2 of meiosis?
Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not. This occurs in meiosis I in a long and complicated prophase I, split into five sub-phases. The equatorial plane in meiosis II is rotated 90° from the alignment of the equatorial plane in meiosis I.
