- (2) Ma'am, so during metaphase I, homologue pairs not individual chromosomes line up at the metaphase plate for separation.
- (6) NICE!
- (1) Class we are now in metaphase I art gallery and what is happening during the metaphase I?
- (4) Very good! What is crossing over guys? is it about in traffic in road hahahaha
- (5) No ma'am, when chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
- (4) Those to are correct, good job! Enjoy your last stop in this trip.
- (1) So guys this is the last stage or stop of our trip which is the anaphase I and telophase I. So my question is what is happening during those 2 stages?
- (1) in anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don't come apart.
- (5) Thank you ma'am! Stay safe!
- (1) So guys out field trip finally ends here, i enjoyed the trip and i hope you all enjoyed it too. But i have last question that is what is chiasmata?
- (2) Ma'am, The chiasmata or chiasma if singular is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis.
- (4) That's all guys! Thank you all! Be careful going home
- (3) Goodjob Khen!
- (3) When the homologous pairs line up at the metaphase plate, the orientation of each pair is random.
- (3) Finally, in telophase I, the chromosomes arrive at opposite poles of the cell. In some organisms, the nuclear membrane re-forms and the chromosomes decondense, although in others, this step is skipped—since cells will soon go through another round of division.
