Match the terms with the right definition. Question 1 options: A chart that traces a particular trait through a family history The trait that overshadows or is seen. Represented by a capital letter. When two organisms with similar characteristics are mated. Usually results in defects or abnormalities being passed onto the next generation. The process of breeding two similar organisms to get desired traits. The process of cell division that makes body/somatic cells. Each cell made is diploid and contains double the number of chromosomes as haploid cells. Each cell is an exact copy of the original. Alleles that are the same – RR, rr. The trait that hides in the background. Represented by a lowercase letter. Crossing two genetically different organisms resulting in an organism that is said to have the best traits from both parents. The control center of eukaryotic cells responsible for containing DNA. The physical expression of the trait. Ex. Freckles, round, brown eyes. Unit of heredity which determines the traits you receive. The process of altering the DNA of an organism to get desired traits. The letters that code for a trait – ex. RR, Rr, rr. The process of cell division that has sex cells (sperm and egg). Cells made from meiosis are haploid or half the number of chromosomes as diploid cells. Process of making an exact copy of an organism by copying the DNA of that organism and placing it into an egg cell which is stimulated to divide and create an organism. The letters that represent the traits. Method of adding or deleting genes. The passing of traits from parent to offspring. Carries the instructions that determine the traits of an organism. Alleles that are different – Rr 1. Alleles 2. Dominant 3. Heterozygous/Hybrid 4. Genetic Engineering 5. Selective Breeding 6. DNA (Deoxyribonucleic acid) 7. Recessive 8. Genotype 9. Genes 10. Phenotype 11. Meiosis 12. Homozygous/Purebred 13. Cloning 14. Nucleus 15. Pedigree 16. Mitosis 17. Gene Therapy 18. Heredity 19. Inbreeding 20. Hybridization
