Explore chromosomes and karyotypes with the Amoeba Sisters! This video explains chromosome structure, how chromosomes are counted, why chromosomes are important, and how they can be arranged in a karyotype! This video also tackles a few misconceptions about how chromosomes. Table of Contents: 1:15 What makes up a chromosome? 2:18 Understanding replicated vs. unreplicated chromosome 3:28 Introducing a Karyotype 4:01 Potential Misconception in Karyotype 5:28 XX and XY Chromosomes Vocabulary includes chromosome, centromere, sister chromatids, chromatin, nucleosome, haploid, diploid, homologous chromosomes, gametes, autosomes, and sex chromosomes! Special thanks to Dr. Brian Davis for his expertise in verifying that a typical karyotype would show 2 chromatids per chromosome.

Mutations: The Potential Power of a Small Change
 
07:22
The Amoeba Sisters discuss gene and chromosome mutations and explore the significance of these changes. Music used with permission from Adrian Holovaty (http://www.youtube.com/adrianholovaty). This video has a handout here: http://www.amoebasisters.com/handouts.html We appreciate the feedback we get for clarification or improvements on our videos. At 2:11, we try make the A (adenine) base look upset now that the complementary base T (thymine) has been replaced with a G (guanine) in a point mutation. But we wish we had put more distance between the cartoon bases to clarify, that now, they cannot bond in this way. Note: This can sometimes be fixed by a polymerase in proofreading- but if not fixed- the G may be be matched with a C and the mutation will remain.

Genotypes and Phenotypes
 
12:57
033 - Genotypes and Phenotypes Paul Andersen explains how changes in the genotype of an individual can affect the phenotype. He begins with genotype:phenotype::letters:story analogy. He explains how mutations can be neutral, beneficial or harmful. He also explains how mistakes in the cell cycle can lead to disorder, sterility or new species. Do you speak another language?

Punnett Squares and Sex-Linked Traits
 
06:12
Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video has a handout here: http://www.amoebasisters.com/handouts.html This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out though that when it comes to biological sex- it can be influenced by more than just sex chromosomes X and Y. For example, the SRY gene, plays a major role in human biological sex determination. While this video only focuses on solving sex-linked trait problems in a Punnett square, here are some further reading suggestions to learn about the SRY gene and its role in biological sex. Further Reading Suggestions: (Updated 2018)********** About SRY Gene from NIH: https://ghr.nlm.nih.gov/gene/SRY About SRY and Sex Determination from Harvard: http://sitn.hms.harvard.edu/flash/2016/im-xy-know-sex-determination-systems-101/ *************************************************************** Support us on Patreon! http://www.patreon.com/amoebasisters Our FREE resources: GIFs: http://www.amoebasisters.com/gifs.html Handouts: http://www.amoebasisters.com/handouts.html Comics: http://www.amoebasisters.com/parameciumparlorcomics Connect with us!

Alleles and Genes
 
08:07
Join the Amoeba Sisters as they discuss the terms "gene" and "allele" in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity. Note: as mentioned throughout video, the ability to taste PTC may be more complex than a single gene trait. This video serves as an introduction before exploring Punnett squares in our heredity series: https://www.youtube.com/watch?v=fcGDUcGjcyk&list=PLwL0Myd7Dk1FVxYPO_bVbk8oOD5EZ2o5W This video has a handout! http://www.amoebasisters.com/handouts While this video only focuses on basic understanding of alleles and genes as well as the ability to taste- or not taste- PTC (phenylthiocarbamide), we encourage learning more! Here is a recommended reading that expands on the genetics involved in tasting PTC and includes some of the history in how it was discovered: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3349222/ Support us on Patreon! http://www.patreon.com/amoebasisters Our FREE resources: GIFs: http://www.amoebasisters.com/gifs.html Handouts: http://www.amoebasisters.com/handouts.html Comics: http://www.amoebasisters.com/parameciumparlorcomics Connect with us!

Mitosis vs. Meiosis: Side by Side Comparison
 
06:22
After learning about mitosis and meiosis from our individual videos, explore the stages side by side in this split screen video by The Amoeba Sisters! Expand video details for table of contents. Vocabulary in this video includes chromosome, chromatid, haploid, diploid, crossing over, and homologous chromosomes. Contents: 0:50 Intro to Mitosis/Meiosis 1:07 Starting Cells in Mitosis/Meiosis 1:20 Interphase (happens before mitosis and meiosis) 2:19 Mitosis/Meiosis I Split Screen 4:30 End of Mitosis 4:46 Meiosis II Hope you enjoy our comparison! You can see our individual videos on mitosis https://youtu.be/f-ldPgEfAHI and meiosis https://youtu.be/VzDMG7ke69g We also like to pin extra points/clarifications here. Crossing over in meiosis has a major role in genetically diverse offspring; however, Pinky learned in one of her graduate courses that mitosis crossing over- while very rare (likely why it's uncommon to see it in intro bio courses)- can occur. It can have a role in human cancer and "loss of heterozygosity." While this unusual event is not discussed in this intro video, here is a further reading suggestion where you can learn more about it: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2648873/ . P.S.

Genotype vs Phenotype
 
02:00
Genotype and phenotypesYour genotype is your genetic code of your cells. This genetic code is responsible for many of your traits. The physical expression of your genotype is your phenotype. Your genetic information is stored in your chromosomes on sections called genes. A gene is a portion of DNA that codes for a trait. The following picture illustrates this. If you look at this drawing of a gene, the different sections are your genes. In genetics you will encounter these three types of genotypes. Homozygous dominant is written BB Homozygous recessive Bb And heterozygous recessive bb For each trait you get some information from mom and some from dad. The different forms of the same trait are called alleles. Take a look at the different hair texture. These different forms are alleles. It is still hair, just different forms. A dominant allele will cover up or mask a recessive allele. You will only get a recessive allele if both alleles are recessive. Your phenotype is the actual expression of the genotype. For example this dog has a round nose, this cat has black hair. These are physical expression of the genetic code. -~-~~-~~~-~~-~- Please watch: "Study Skills Teacher's Secret Guide to your Best Grades" https://www.youtube.com/watch?v=f3bsg8gaSbw -~-~~-~~~-~~-~- * * For more Life Science videos and summaries see, http://www.moomoomath.com/Middle-School-Science-and-Biology.html
