What is the longest stage of meiosis?
It is prophase because it is where chiasmata is formed and crossing over between non sister chromatids of homologous chromosomes happen. it is further divided into 1.diplotene2.zygotene3.pachytene4.leptotene and5.diakinesis stages
What major chromosomal event occurs between leptonema and zygonema?
After condensing into long strands in the nucleus during Leptotene/Leptonema Chromosomes line up approximately with each other into homologous pairs. Telomeres cluster at one end of the nucleus and synapsis (pairing together of the homologous chromosomes) takes place in Zygotene/Zygonema.

How does prophase you differ from prophase II?
At the beginning of telophase I, each half of the cell has a complete haploid set of chromosomes, but each chromosome is still composed of two sister chromatids. Cytokinesis usually occurs simultaneously with telophase I, forming two haploid daughter cells. No chromosome replication occurs between the end of meiosis I and the beginning of meiosis II, as the chromosomes are already replicated. In telophase II, the nuclei form and the chromosomes begin decondensing. The meiotic division of one parent cell produces four daughter cells, each with a haploid set of (unreplicated) chromosomes.
Describe the two stages in meiosis?
there are actually four stages or phases in meiosis: prophase, metaphase, anaphase and telophase. Within prophase there is the leptotene stage where individual chromosomes condense into strands within the nucleus, the zygotene stage where the chromosomes line up with each other into homologous chromosomes, the pachytene stage where the nonsister chromatids exchange genetic information over regions of homology, the diplotene stage where the chromosomes start to separate and uncoil a little to allow some transcription of DNA, and the diakinesis stage where the chromosomes condense further and the meiotic spindle begins to form.
How is prophase1 different in meiosis than in mitosis?
on prophase of mitosis the cylindrical shaped structure(centrioles) starts to move going to the both opposites sides as they move the fiber make-up structure starts to form(spindle). The spindles is the one who controls the movement of the choromosomes while it is in the process. note the chromosomes starts to become shorten ad thick that's why they r very easy to see. in prophase I of meiosis the choromoses condense and are seen to have splitinto two chromatids. One of its important features of the phrophase I of meiosis the paternal and maternal chromosomes come together in homologous pairs., well that's my answer i know its ryt... hope that i have helped you. -joan- The answer by joan simply states the processes that occur individually by mitosis and meiosis. The question is to discuss the 'Difference' instead of state the events that occur. In my understanding, prophase 1 of meiosis consists of 5 different stages - Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. Now the question is which of these 5 stages differ from prophase of mitosis. I found that stages Leptotene (condensation of DNA) and Diakinesis (nuclear envelop fragments) are similar to that in prophase of mitosis. Thus, the difference has to lie in stages Zygotene (formation of bivalents and synaptonemal complex), Pachytene (crossing over at sites called chiasma) and Diplotene (separation of synaptonemal complex). Do improve on my answer. glenn
What are the steps of prophase 1?
1) leptotene (early chromatin condensation), 2) zygotene (localized condesations and chromomere becomes visible), 3) pachytene (chromatin condensation continues), 4) diplotene (homologs seem to repel one another, but held together at chiasmata. also now it can be seen that each homolog has 2 chromatids), and 5) diakenesis (shortening and thickening of the paired chromosomes, formation of the spindle fibers, disappearance of the nucleolus, and degeneration of the nuclear membrane)
What are the five phases of meiosis 1?
Meiosis.....................produces gametes or sexual cells, which contain half the chromosomesbecause the sexual union of male and female will contribute the otherhalf.
