shortest phase of prophase1
Answers
Answer:
Meiosis prophase 1
Prophase 1 of Meiosis is the first stage of meiosis and is defined by five different phases; Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis[1] (in that order). Prophase 1 is essentially the crossing over and recombination of genetic material between non sister chromatids[2] - this results in the genetically unidentical, haploid daughter chromatid cells.

Leptotene
Leptotene is the first of five stages of Prophase 1 and consists of the condensing of the already replicated chromosomes, this procedure continues throughout Prophase 1. The chromosomes become visible by using electron microscopy, which can distinguish between sister chromatids[3]. The appearance of the chromosomes at this stage of Prophase 1 is likened to 'a string with beads'[4], these beads are called chromomeres. Each sister chromatid is attached to the nuclear envelope and are so close together that they can be mistaken for only one chromosome[5]. This is a very short stage of Prophase 1.
