Prophase 1 is the beginning phase of meiosis while prophase 2 is the beginning phase of prophase 2. There is a long interphase before prophase 1, whereas prophase 2 occurs without an interphase.
What is the key difference between prophase and prophase 1?
Each meiosis has four stages. Prophase I is the beginning phase of meiosis I while prophase II is the initial phase of meiosis II. This is the key difference between prophase I and prophase II. Another difference between prophase I and prophase II is the possibility of crossing over and mixing genetic material.
What is the major difference between prophase one and prophase two?
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 is different between prophase 1 of meiosis and prophase of mitosis?
During prophase I, the chromosomes condense, as in mitosis. However, the homologous chromosomes also pair in prophase I. … Unlike in mitosis, the sister chromosomes stay together through meiosis I, but the homologous chromosomes are separated. Each homologous chromosome carries different alleles for each gene.
Which of the following statements best describes a key difference between the processes of mitosis and meiosis?
Which of the following statements BEST describes a key difference between the processes of mitosis and meiosis? Mitosis creates identical, diploid daughter cells, whereas meiosis creates genetically unique, haploid daughter cells.
What is the difference between Telophase 1 and 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 is the difference between prophase and telophase?
As nouns the difference between telophase and prophase
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.
How can you tell the difference between meiosis 1 and 2?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas Meiosis I produces 2 diploid daughter cells.
What’s the difference between anaphase 1 and 2?
Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.
What is the purpose of prophase 1?
Prophase I highlights the exchange of DNA between homologous chromosomes via a process called homologous recombination and the crossover at chiasma(ta) between non-sister chromatids. Thus, this stage is important to increase genetic variation.
What are 2 differences between mitosis and meiosis?
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. … Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis. Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid.
What happens in prophase 1 of mitosis?
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.
Which of the following accurately describes a difference between cytokinesis and mitosis?
Which of the following best describes the difference between mitosis or M phase and cytokinesis? Mitosis takes place in animal cells; cytokinesis takes place in plant cells.
Which of the following best describes the difference between diploid and haploid?
The most obvious difference between Haploid and Diploid is the number of chromosome sets that are found in the nucleus. Haploid cells are those that have only a single set of chromosomes while diploid cells have two sets of chromosomes.
What are the main differences between these two processes and what types of daughter cells produced by each?
What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
