This is a 12 minute HD video choreographed to dramatic music designed to provide a visually stunning and comprehensive review of the process of Meiosis cell division the production of sperm and egg or pollen and ovum. This is so lets see all of this is meiosis I. First lets start with mitosis.
These haploid cells are the gametes that could go on to produce an offspring through sexual. Crossing over meiosis I meiosis II and genetic variation. And so let me draw the cell right over here.
A couple of things happen. Httpsgoogluf6hh4-- DNA Replication Video. The primary events that occur during mitosis are interphase the cell prepares for division by replicating its genetic and cytoplasmic material.
Hi and welcome to this video on cell replication otherwise known as mitosis or meiosis. Interphase can be further divided into G1 S and G2. This dramatic video choreographed to powerful music introduces the viewerstudent to the wonder and miracle of the cell division and cell cycle.

And if you wanna be precise mitosis is the process by which this one nucleus will turn into two nuclei that each have the.
Crossing over meiosis I meiosis II and genetic variation. So this is all meiosis meiosis I here and you can see each of these cells now have a haploid number. The first division meiosis I results in two unique daughter cells that have half the amount of DNA as the parent germ-line cell.
There are two cell division events during meiosis. So lets see what happens in prophase I. Unlike mitosis meiosis is a reduction division the chromosome number is halved from diploid 46 chromosomes in 23 pairs in humans.
Now each of those two chromosomes do. Then theres prophase the chromatin thickens.
