Quick Answer: What are the similarities between prophase 1 and prophase 2?

How does prophase one differ from prophase two?

In meiosis, how does prophase I differ from prophase II? During prophase I there is one diploid cell; during prophase II there are two haploid cells.

What is the difference between prophase I and prophase II quizlet?

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.

How is prophase I of meiosis different from both prophase II of meiosis and mitotic prophase?

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 are 2 parts of meiosis that are similar to mitosis?

Aside from these two distinct purposes, both mitosis and meiosis occur in multiple stages during which the same general things happen: DNA replication and condensation, nuclear membrane degradation, spindle formation, chromosomal segregation and nuclear reformation.

What is the difference between meiosis 1 and 2 quizlet?

Meiosis I is a reduction division where only one member of a homologous pair enters each daughter cell which becomes halploid. Meiosis II only splits up sister chromatids.

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 occurs in prophase 1 that 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 are the major differences between prophase in mitosis and prophase one of 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.
