Meiosis with the amoeba sisters

Amoeba Sisters - Meiosis We watched this video in class the other day. If you didn't watch this video the other day, please watch it now. Answer the questions below it. If you already watched, but need to re-watch, feel free to do so. When does the cell duplicate its DNA (make a second copy of the DNA) for meiosis? it only duplicates the DNA for mitosis during interphase, before meiosis starts during prophase I during interphase, after meiosis is complete What process do recombinant chromosomes result from that gives new combinations of the genes on the chromosomes? synapsis tetrad crossing over replication How many chromosomes are found in the body (somatic) cells of a human? 23 46 92 How many chromosomes are found in the gametes (egg and sperm) of a human? 23 46 92 Stages of Meiosis Click on the LINK (the purple title above these instructions). Read through the stages of meiosis summary, study the image, and play through the animation of meiosis before answering the questions below. Meiosis Interactive What is the diploid number for the beginning germ cell for the ANIMATION at the bottom of the page? 2 3 4 5 6 What is the number of chromosomes in the gametes at the end of the ANIMATION at the bottom of the page? 1 2 3 4 6 Is that final number of chromosomes diploid or haploid? diploid haploid Are the chromosomes in the gametes at the end of the ANIMATION of meiosis identical? How do you know? Snurfle Meiosis and Genetics (HTML5) Click on the title above so that you can get to the Snurfle Meiosis interactive. ONLY complete the Meiosis Interactive - you do not have to complete any other portions. Do not save any of your items When finished, answer the question below. Snurfle Meiosis Interactive Meiosis VS Mitosis Use your notes to sort each item into whether it is part of mitosis, meiosis, or both processes! Mitosis daughter cells are diploid cell goes through 1 division 2 daughter cells are created process occurs in body cells daughter cells are identical to the parent cell Meiosis daughter cells are haploid goes through 2 divisions 4 daughter cells are created process occurs in germ cells daughter cells only share some of the genetic material as the parent cell Both DNA must replicate Interphase occurs before use the stages of PMAT
