Cell cycle: Meiosis Steps Explained in Detail
HTML-код
- Опубликовано: 2 июн 2023
- Hi, thanks for watching my video about Meiosis of Cell cycle or Cell Division
In this video I'll walk you through:
- Overview of Meiosis: In this section you will learn a brief concept of Meiosis
- Meiosis occurs in gametes: you will learn the spermatogenesis and Oogenesis process in brief.
- You will understand the Importance of Meiosis:
Whereas in diploid organisms, mitosis produces two daughter cells with full diploid complements, meiosis produces gametes or spores that are characterized by only one haploid set of chromosomes. During sexual reproduction, haploid gametes then combine at fertilization to reconstitute the diploid complement found in parental cells.
Another major accomplishment of meiosis is to ensure that during sexual reproduction an enormous amount of genetic variation is produced among members of a species.
Such variation occurs in two forms. First, meiosis produces gametes with many unique combinations of maternally and paternally derived chromosomes among the haploid complement, thus ensuring that following fertilization, a large number of unique chromosome combinations are possible.
The second source of variation is created by the meiotic event referred to as crossing over, which results in genetic exchange between members of each homologous pair of chromosomes prior to one or the other finding its way into a haploid gamete or spore.
- Stages of meiosis: Meiosis 1 and Meiosis 2
- Stages of Prophase 1: leptotene, Zygotene, Pachytene, Diplotene, Diakinesis
- Crossing over and Synapsis: when homologous chromosomes come close to each other and joined by centromere this process is called synapsis. After synapsis homologous chromosomes exchange parts between by the process of crossing over. After crossing over a cross shap structure appear called chiasma or chiasmata.

Awesome explanation Sir! Thank you so much.❤
Thank you❤ sir for always helping us. Now i am clearing doubts for cpet exams from here. You means a lot to me😇.
For the first time my concept is cleared regarding this topic ....thank u Soo much sir ❣️❣️❣️❣️❣️❣️❣️
Thank u ❤ benefitting from Nepal
ډیرخکلےلیکچر
ډیر مذیدار لیکچر
❤️❤️❤️❤️❤️
Aaj tak maine aapse se accha biology ka teacher kabhi nhi dekha aapke video lectures bahut hi chhote hote hai pr wo bahut hi detail me hote hai jisme aap har ek concepts clear kar dete hai aur hamare saare doubt clear kr dete hai
buhat shukriya hosla afzai k liye...
Sir aapne kingdom fungi kam detail se kyon padhaya hai
App k lectures sun kr papers dy kr atti hon thanks a lot for such lectures...Allah bless you..
Alhamdulillah
Thank you so much, you have cleared all my doubts
Your writing and method of teaching👌
Very great explanation. Thank you Sir!
Thank God i found this lecture!!
Mashallah sir g buht acha lecture ha
tq ,, apke iss lecture k wajah se mujhe bade aasani se cell cycle samajh aa gaya
now i can able to ans. any questn related to these topic
Outstanding lecture 👍
Amazing 😍
Thank you sir😊
Thank you for your efforts 🎉🎉🎉🎉
watching from Bangladesh...
Great work Brother..This video made the topic easy for me..

Good lecture 💞 SIR
Like Those who are from 9th Class ❤📈
Two weeks before exam 😂😂
Hellow advance students😓
Very well done sir 😍😍
Thanks sir g
I am watching from Bangladesh.Sir put Bengali or English caption on the video.Then millions of views will come from Bangladesh.Your presentation is very nice.please sir please
Sir keya smile ha asa smile sa lacture be mazza krta qaim sa sir very very very very nice with smile

We want ur lecture on tissues and their functions
❤❤
Lepotene mn Jo 2 chromosome hn wo ek mother Ka or ek father Ka hai?
Sir nuclus ks waja sa disappear hota ha
❤
Sir pro phase ka step ma jo chromosomes ha male ka ya femal ka ya both
Please kindly do the english version... Your lecture seems interesting but i dont understand your language
❤❤❤❤❤❤❤
Jay shree ram sir 🙏
Sir..aslam o alaikum..sir..jb ap na..stages of prophase1...study kraya tuu ap hans rhy ha....😂😂..like zygotene..ma...
Agr 2 chromosome ek mother or father Ka hai to phr wo homologous hn us Ka kya mtlb?
Sir kindly provide lectures of all topics from ch 10,class XI
Ncert Class 11
2 se 4 chromosome kaise hue
Ek bhi word ache se nhi dikhh rha kya study kre
Caption the skin in English or Bengali.please sir
Thank you sir😊
