The key difference between prophase I and prophase II is that the prophase I is the beginning phase of meiosis I, and there is a long interphase before it while the prophase II is the first phase of meiosis II without an interphase prior to it.
What is the difference between prophase mitosis prophase I prophase II?
Prophase occurs in mitosis, and prophase I occurs in the first division of meiosis, meiosis I. Prophase II occurs in the second division of gametic cells, and is distinguished by the chromosomes condensing and the centrosome dividing to either side of the cell. 3.
What is the difference between 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 happens in prophase 1 and 2 of meiosis?
The first is the condensation of chromatin into chromosomes that can be seen through the microscope; the second is the synapsis or physical contact between homologous chromosomes; and the crossing over of genetic material between these synapsed chromosomes.
What is the one major difference between prophase in mitosis and prophase I in meiosis?
In mitosis, prophase, metaphase, anaphase and telophase occur once. Chromosomes condense and the centrosomes begin to form an early spindle. Meiotic prophase I is much longer that mitotic prophase. During prophase I homologous chromosomes make contacts with each other called chiasmata and “crossing over” occurs.
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 is the difference between prophase in mitosis and prophase 2 in meiosis?
In prophase of mitosis, each chromosome is represented twice i.e. both members of a homologous pair are present in cell but in prophase II of meiosis, each chromosome is represented once i.e. only one member of the homologous pair is present.
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 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 happens in prophase I?
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 happens during prophase II?
During prophase II, the chromosomes condense, and a new set of spindle fibers forms. The chromosomes begin moving toward the equator of the cell. During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells.
What are the differences between meiosis and mitosis How do these differences support the purpose of each?
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells.
What are the main differences between mitosis and meiosis?
What Is the Difference Between Mitosis and 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|
