What are we going to be learning about today Mr. Corpuz ?
Well class, since you seem so interested, today we will be discuss about meiosis.
Duplicated homologous chromosomes (red andblue) pair up and exchange segments.
Excuse me sir, may i go out?
Prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes.
Sure. So, okay class the first step in meiosis is Prophase I.
She went to the bathroom 5 minutes ago. Ugh.
Chromosomes line up by homologous pairs.
The next stage ismetaphase IIn metaphase I, the homologous pairs of chromosomes align on either side of the equatorial plate
The two homologous chromosomes of each pairseparate.
Interesting..
And, also the next stage is Anaphase I, The spindle fibers contract and pull the homologous pairs, each with two chromatids, away from each other and toward each pole of the cell
Oh! That sounds cool!
Wow!
Then the last in meiosis I is Telophase I and Cytokinesis
When telophase I begins, each half of the cellhas a complete haploid set of duplicatedchromosomes..
Cytokinesis usually occurs simultaneouslywith telophase I, forming two haploiddaughter cells..
Thankyou for helping me understand!!
Two haploid cells form; each chromosome stillconsists of two sister chromatids.
