Reading Genes

Dive into the world of genetics and explore the factors that lead to variation in populations. Learn about essential genetic definitions and concepts like alleles, phenotypes, and genotypes. Discover how genes shape our physical traits and how alleles determine dominant and recessive characteristics. Create your own genetic larkey to visualize these concepts in action.

  1. Reading Genes October 11, 2019 - Page 47

  2. Essential Question What leads to variation in a population?

  3. Definitions to Remember Feature - An inheritable characteristic (a category - hair color) Trait - An expression of a feature (a fact - blue eyes) Variation - All the traits that appear in a population together

  4. Definitions from Yesterday Genome - The entirety of genetic information in your cells Chromosome - The bodies in your nuclei that contain the information (DNA wrapped around protein) DNA - The twisted ladder molecule that carries genetic information. A recipe for proteins.

  5. More Definitions from Yesterday Protein - A molecule that makes up your body and enables it to do all the things it needs to do Gene - A piece of DNA that codes for one protein Allele - One half of a gene - either the half from a mother or a half from a father

  6. Larkey Features and Traits

  7. New Words Genotype - All the genes of an organism put together - what its DNA says Phenotype - All the traits of an organism put together - how it looks

  8. Alleles and Genes If an allele is dominant, it will always show up as a trait If an allele is recessive, it only shows up when both alleles in the gene are recessive A gene with two identical alleles are homozygous A gene with two different alleles are heterozygous

  9. So What Does That Mean? Note: Fur is a case of incomplete dominance. Neither side wins

  10. Let’s Draw a Larkey!

  11. Now It’s Your Turn Flip a coin Heads is Big A (short legs), Tails is Little a (long legs) Flip a second time for A Now Flip twice for E, F, and T You should have eight flips when you’re done - this is your larkey’s genotype Now draw its phenotype
