Which of the following best describes the major difference between prophase 1 of meiosis and prophase of mitosis?

What is the major difference between prophase 1 of meiosis and prophase of mitosis?

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. This is where chromosomes exchange sections of DNA.

What is the main difference between the chromosomes in prophase I of meiosis and prophase II of meiosis?

Chromosomes no longer remain in paired condition at the beginning of prophase II and the stage is not eventful, i.e. not subdivided in substages. Each chromosome is with two chromatids, but in prophase II chromosome number is just half of what it was in prophase I. It ends to pave way for metaphase II.

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.

Which statement best describes a major difference between meiosis one and meiosis two?

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. Genetic recombination (crossing over) only occurs in meiosis I.

How can you tell the difference between prophase and prophase I?

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 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 interphase 1 and 2?

The Phases of Meiosis II

Meiosis II may begin with interkinesis or interphase II. This differs from interphase I in that no S phase occurs, as the DNA has already been replicated. Thus only a G phase occurs. Meiosis II is known as equational division, as the cells begin as haploid cells and end as haploid 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 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.

Which characteristics seen in prophase 1 does not occur in prophase 2?

In prophase I, the first stage is known as leptotene. This stage involves the unwinding of the DNA structure to enable an exchange of alleles between homologous chromosome pairs. No crossing over occurs in prophase II. Therefore, prophase II does not feature leptotene.

What happens in 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.

How can you tell the difference between metaphase 1 and 2?

Metaphase 1 is associated with meiosis 1 whereas the metaphase 2 is associated with meiosis 2. The main difference between metaphase 1 and 2 is that chromosomes are attached as homologous pairs at the equator during the metaphase 1 and during metaphase 2, single chromosomes are attached at the equator.

Which of the following statements best describes the major differences between metaphase 1 of meiosis and metaphase of mitosis?

Which of the following statements best describes the major difference between metaphase I of meiosis and metaphase of mitosis? … The process of meiosis has two divisions resulting in four haploid daughter cells, while mitosis has one division resulting in two diploid daughter cells.

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 one of the very important differences between mitosis and meiosis quizlet?

What are the principal differences between mitosis and meiosis? Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells.
