Understanding Genetics: Key Concepts and Vocabulary in Genetics and Cell Division

This review covers essential topics in genetics, including phenotype, genotype, genetic traits, and disorders associated with inheritance. Key concepts such as sex-linked traits, cell division (mitosis and meiosis), and common genetic disorders like hemophilia and cystic fibrosis are discussed. It features vocab questions to test knowledge on allele characteristics, heredity, and the genetic makeup of organisms. Users can interactively choose answers to reinforce their understanding. This review serves as a valuable resource for students learning basic genetics and cell division.

  3. A ________________ is the genetic make-up of an organism. • phenotype • genotype • letter • number Vocab 1

  4. An example of a phenotype: • Eye color • genotype • Shirt color • Bb Vocab 2

  5. The parts that make up a gene are called: • Parents • Animals • Plants • Alleles Vocab 3

  6. An example of the homozygous genotype: • Hh • Bb • bb • hH Vocab 4

  7. The study of heredity: • genetics • biology • science • hereditology Vocab 5

  8. When two or more genes affect a trait: • Multiple alleles • Incomplete dominance • Codominance • Polygenic inheritance Vocab 6

  9. A carrier has: • Multiple alleles • One dominant, one recessive • Codominance • Polygenic Inheritance Sex-Linked 1

  10. One example of a sex-linked trait is: • genotype • foot size • hair color • colorblindness Sex-Linked 2

  11. A disorder that produces abnormal red blood cells • Hemophilia • Sickle Cell Disease • Cystic Fibrosis • Down Syndrome Disorders 1

  12. The disorder that has an extra chromosome • Hemophilia • Sickle Cell Disease • Cystic Fibrosis • Down Syndrome Disorders 2

  13. A person that has hemophilia has problems with: • Blood clotting • Blood cells • Fear of blood • Low hemoglobin Disorders 3

  14. The disorder that causes a person to have thick mucus in their lungs & intestines: • Down Syndrome • Hemophilia • Cystic Fibrosis • Sickle Cell Disease Disorders 4

  15. The first stage of cell division, before mitosis begins: • Interphase • Prophase • Metaphase • Cytokinesis Cell Division 1
