- الانزلاق: 1
- definitely lets go inside and ill teach you all about it! lets start off with MEIOSIS' purpose is to produce gametes for sexual reproduction
- hey ! we have a test later on and i really don't know anything about meiosis! Can you please explain it to me?
- الانزلاق: 2
- Humans have 23 pairs of chromosomes totalling in 46. There are a pair of sex chromosomes, X and Y.
- i think this is all coming back to me! The haploid cells have single sets of chromosomes, while diploid cells have two sets of chromosomes.
- YES ! YOU GOT IT
- الانزلاق: 3
- These are the stages of meiosis PROPHASE Ichromosomes pair up and cross over, nuclear envelope break down and spindle forms METAPHASE I homologous chromosomes pairs line up near the cell equatorANAPHASE I homologous chromosomes are pulled to opposite poles of the cellTELOPHASE I CYTOKINESISnuclear envelopes reform around the separated chromosomes, resulting in 2 haploid daughter cells
- الانزلاق: 4
- Prophase iinuclear envelope breaks down and the chromosomes condense Metaphase iiall chromosomes line up at the cell equator Anaphase ii sister chromatids separate and move to the opposite cells Telophase iicytokinesis divides the cells into four haploid daughter cells
- الانزلاق: 5
- I really needed all of this! Thank you so much.
- Crossing over is very important for meiosis and is when they swap DNA with each other. Meaning crossing over creates new combinations of genes. Now in genetic diversity crossing over contributes because it creates a new combination of genes that can be passed on to offspring.
- الانزلاق: 6
- okay everybody its time to put all our things away and take this test !
- WE'RE GONNA ACE THIS !
