1. Genes1 The factors that control the traits

Notes

1. Genes: The factors that control the traits 2. Chromosome: The threadlike structure that carries heredity information (DNA) 3. Alleles: The different forms of the genes 4. DNA: A molecule that stores information for making a living thing 5. Genotype: The allele combination or genetic makeup of an organism 6. Purebred: An offspring that has many generations of the same trait 7. Phenotype: An organism’s physical appearance for the traits it has 8. Chromosome Theory: This theory states that genes are carried from parents to offspring on chromosomes 9. Heredity: The passing of characteristics from parents to offspring 10. Recessive Allele: The allele that is hidden whenever a dominant allele is present 11. Hybrid: An organism that results from the breeding of two genetically different individuals 12. Punnett Square: A square used in genetics to calculate the frequencies of different genotypes and phenotypes among Offspring. 13. Codominance: The alleles are both dominant so both traits are seen in the offspring 14. Homozygous: An organism that has two of the same alleles for a trait 15. Dominant Allele: The allele whose trait always shows up if the allele is present 1...
