Unit Exam Review

2. a plant that produces seeds that are exposed rather than seeds enclosed in fruits
3. a cell that contains a full set of chromosomes
5. situation in which both alleles of a gene contribute to the phenotype of the organism,
8. when an organism has two of the same alleles for a specific gene (AA or aa)
12. molecule that contains an organism's blueprint for life
14. flower plant, most advanced type of plant on Earth, most adapted
15. a characteristic or feature of an organism
16. a certain region of the DNA molecule that codes for a specific genetic trait
17. a single molecule of DNA
19. the physical appearance/characteristics of the organism that is seen
21. the trait that is masked by the dominant allele
22. in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes

1. X-shaped structures, made up of DNA
4. Insects and animals move pollen from the stamen (via anther) to the pistil (ovary)
6. father of genetics, Austrian monk, studied pea plants
7. type of dominance where an intermediate phenotype or in-between mix of traits is seen
9. change in a DNA sequence that affects genetic information
10. the combination of alleles that an individual has for a certain gene
11. an organism has two different alleles for a certain gene (Aa)
13. a cell that contains only half of the total chromosomes, haploid cells are gametes
16. the study of inheritance
18. one of the versions of a gene inherited from the father or mother
20. a process in cell division during which the number of chromosomes decreases to half the original number, creates the gametes
