A pachytene is the third prophase of meiosis, during which the chromosomes shorten and divide into four chromatids.
Crossing over occurs during prophase I of meiosis, specifically during the pachytene stage. This is when homologous chromosomes exchange genetic material, leading to genetic variation among the resulting gametes.
Recombinant DNA is made during the crossing over stage of meiosis, specifically during prophase I. This is when homologous chromosomes exchange genetic material, leading to the formation of new combinations of genes.
The synaptonemal complex disappears during the diplotene stage of meiosis. This dissolution marks the end of the physical connection between homologous chromosomes, allowing them to separate and continue with the process of meiosis.
The stage when all the cells show crossover chromosomes is the pachytene stage of meiosis. During this stage, homologous chromosomes pair up and exchange genetic material through a process called recombination or crossing over, which results in the formation of new combinations of genetic information.
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
pachytene
prophase 1.
The longest phase in meiotic division is prophase I. This phase involves significant chromosomal changes, including crossing over and genetic recombination, which contribute to genetic diversity. It is divided into subphases: leptotene, zygotene, pachytene, diplotene, and diakinesis.
Crossing over occurs during prophase I of meiosis, specifically during the pachytene stage. This is when homologous chromosomes exchange genetic material, leading to genetic variation among the resulting gametes.
Recombinant DNA is made during the crossing over stage of meiosis, specifically during prophase I. This is when homologous chromosomes exchange genetic material, leading to the formation of new combinations of genes.
The synaptonemal complex disappears during the diplotene stage of meiosis. This dissolution marks the end of the physical connection between homologous chromosomes, allowing them to separate and continue with the process of meiosis.
Chiasmata are observed during the prophase I of meiosis. Chiasmata are the physical manifestation of crossing over between homologous chromosomes, where genetic material is exchanged between chromatids.
Crossing over between pairs of homologous chromosomes to form chiasmata is known as pachytene. It occurs during prophase I in meiosis.?æ
Nonsister chromatids cross over during prophase I of meiosis, specifically during the substage called the pachytene stage. This crossover process allows for the exchange of genetic material between homologous chromosomes and contributes to genetic diversity in the resulting daughter cells.
Crossing over occurs during prophase I of meiosis I in oogenesis, which is when homologous chromosomes exchange genetic material. This process increases genetic diversity by shuffling genetic information between maternal and paternal chromosomes.
The longest phase of meiosis is prophase I, which involves chromosome condensation, crossing over, and nuclear envelope breakdown. This phase can be subdivided into early, mid, and late stages, making it the most time-consuming phase in the process of meiosis.
The stage when all the cells show crossover chromosomes is the pachytene stage of meiosis. During this stage, homologous chromosomes pair up and exchange genetic material through a process called recombination or crossing over, which results in the formation of new combinations of genetic information.
