Across
  1. 4. Actin:Is a cell protein. Used in muscular contraction, cellular movement and helps contain the cell shape.
  2. 5. Homozygous:Having 2 of the same allele for a gene (GG, gg)
  3. 6. Trait:A characteristic or feature of an organism.
  4. 7. Codominance:Both alleles mix and their offspring's features equally show both traits. (Cow with black and white spots)
  5. 9. Genotype:Genetic makeup (GG) (Gg) (gg)
  6. 10. Recessive:Is a trait that is only expressed when the genotype is homozygous (gg)
  7. 13. Myosin:Activating protein of muscular contractions. Works with actin to create sarcomere.
  8. 14. Incomplete Dominance:When neither allele is fully dominant, so both alleles mix and their offspring has a blended phenotype.
  9. 15. Allele:Different forms of genes which can cause different forms of proteins which leads to variations in a trait.
Down
  1. 1. Phenotype:The physical look of the trait (blue eyes)
  2. 2. Chromosome:Found in the cell's nucleus. Made of bundles of DNA.
  3. 3. Heterozygous:Having 2 different alleles for a gene (Gg)
  4. 7. Complete Dominance:The dominant variation completely masks the recessive trait (Gg)
  5. 8. Gene:Segment of DNA that provides code for proteins of cellular function.
  6. 11. DNA:Deoxyribonucleic acid, carries the genetic instructions for all living organisms.
  7. 12. Sarcomere:Basic contractile muscle tissue unit. Made of actin and myosin, is responsible for muscle contractions.
