The letters “Tt” would represent an organism that is ___________________________________.

2. __________________________ alleles only show up when there are two of the same kind and are generally represented by a lowercase letter. 3. Factors that control traits are called _______________________. 4. Dogs, like poodles, are called _____________________ because they always produce the same offspring as the parent. 5. The term referring to passing genetic information from parent to offspring is _______________________. 6. Different forms of a gene are called _______________________. An example would be eye color: you can have brown, hazel, green, or blue. 7. _______________________ is the likelihood that an event will occur and is not affected by past history. 8. An organism’s ____________________ is its physical appearance, or visible traits. 9. In __________________________ both parents’ alleles contribute to the offspring’s phenotype. An example would be mating a white horse and a black horse to get a black spotted horse. 10. Different characteristics passed from parent to offspring are referred to as ________________. Mendel studied these in pea plants when he looked at the height of different plants. 11. The letters “TT” would represent an organism that is ___________________________________. 12. __________________________ alleles are generally represented by a capital letter and are always expressed when they are present. 13. An organism’s ____________________ is its genetic makeup, or allele combinations. 14. In ____________________________________ one specific allele for a trait is not totally dominant over the other. An example would be mating a white flower and a red flower to get pink flowers. 15. The letters “tt” would represent an organism that is ___________________________________. 16. A ________________________ has two different versions of an allele. We may also call them heterozygous.
