Across
  1. 4. divides the chromosome into two arms: the short arm p and q arm long arm
  2. 7. Chromosomes are located inside the nucleus of the cell.
  3. 9. Father of Genetics
  4. 10. A genetic code that determines specific traits in an organism.
  5. 12. Chromosomes come in matched sets called homologous pairs 1 from mom and 1 from dad.
  6. 15. Dominance When no alleles are dominant, heterozygous offspring will not display either parental phenotype.
  7. 16. Physical characteristics
  8. 17. Organisms inherit physical traits from their parents through genetic information passed down across generations.
  9. 18. Squares visual diagram used to calculate and predict gene combinations resulting from a genetic cross.
  10. 19. When 2 or more alleles are dominant, the heterozygous offspring will show both dominant phenotypes simultaneously.
Down
  1. 1. Different forms or variations of a gene.
  2. 2. Organisms that have 2 different alleles for a particular trait.
  3. 3. Transmission Genes are passed through the joining of two haploid gametes to create a new diploid zygote.
  4. 5. Alleles Genes that have more than two alleles
  5. 6. Organisms that have 2 identical alleles for a particular trait.
  6. 8. Specific combinations of dominant and recessive alleles determine which phenotypes are expressed in offspring.
  7. 11. Inheritance Studied the inheritance of traits—specific characteristics passed from parent to offspring
  8. 13. Traits Single gene traits
  9. 14. Genetic (gene) material
  10. 18. Traits Traits controlled by two or more genes
