Across
  1. 4. The chance/how likely an offspring is of having a particular phenotype
  2. 6. Squares is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
  3. 7. The young creation of living organisms. Example: children
  4. 9. It is one of two or more versions of DNA sequence
  5. 10. They show their effect/trait with two copies of the allele. Traits that get hidden by dominant traits.
  6. 13. It is the scientific study of genes and heredity.
  7. 14. The genetic makeup of an individual cell or organism
  8. 17. They show their effect/trait with only one copy of the allele. Traits that hide other traits when passed on to offspring.
  9. 19. The transfer of traits from one generation to another generation.
  10. 20. Physical characteristic of an organism that is not passed down to offspring genetically. It can be a learned trait, or a product of the environment’s influence on the organism.
Down
  1. 1. Means that it carries two copies of the same recessive allele. Example: (bb)
  2. 2. Means that it carries two copies of the same dominant allele. Example: (BB)
  3. 3. Thread-like structures that are found in the nucleus of a cell that contains all DNA. Each is made of protein and a single molecule of DNA. Comes in matching sets of two (diploid). Human cell nucleus contains 46 of these (23 pairs).
  4. 5. A characteristic or features of one organism that are inherited (passed from parent to offspring).
  5. 8. They determine traits. A stretch of DNA on a chromosome with instructions for one trait.
  6. 11. The set of observable characteristics or traits of an organism.
  7. 12. Means that it carries two different alleles. Example: (Bb)
  8. 15. A molecule that carries the genetic instructions for all living organisms. Short for deoxyribonucleic acid. Contains the specific instructions that make each type of living creature unique, and determines how the cells in a body will function.
  9. 16. Known as the “father of modern genetics.”
  10. 18. A small egg-shaped structure inside the cell that acts like the brain of the cell. It tells every part of the cell what to do, it contains chromosomes and genes, and stores the cells hereditary material or DNA
