Across
- 1. having gene versions that are different-also called hybrid
- 6. a type of large molecule-made of amino acids that performs important functions inside organisms
- 9. the parts of the cell that build protein molecules based on instructions from genes
- 11. any difference in traits between individual organisms
- 13. the allele combination of an individual organism like BB or Bb
- 14. the part of a cell where chromosomes-DNA/genes are found
- 15. when this gene is present-it expresses itself more strongly all by itself than any other version of the gene
- 17. A chunk of DNA on a chromosome that codes for a trait -also instructions for making a protein molecule.
- 19. A tool used by geneticists to visualize all possible allele combinations
- 21. often called the father of genetics
- 22. to receive genes from a parent
Down
- 2. an organism produced as a result of reproduction
- 3. when a male and a female reproductive cell combine to create an offspring
- 4. a random change to a gene that sometimes results in a new trait
- 5. a pedigree is a genetic representation of a family tree that diagrams the inheritance of a trait or disease though several generations
- 7. A recessive gene is a gene whose effects are hidden in the presence of a dominant gene.
- 8. having gene versions that are the same-also called pure or purebred
- 10. the appearance or physical feature of what a living thing looks like-for example blue eyes
- 12. a type of molecule that genes and chromosomes are made of
- 16. a long piece of DNA that contains many genes
- 17. the study of how hereditary traits are passed between generations
- 18. different forms of a gene are called alleles-a specific form of a gene that provides instructions for making a particular protein molecule
- 20. a specific characteristic of an individual organism
