Genetics and Heredity

3. When pollen from a plant lands on the pistil of the same plant, causing reproduction.
5. When the two alleles in the genotype are the same.
7. A section on a chromosome that has genetic information for a specific trait.
12. A genetic factor that is blocked by the presence of a dominant trait.
13. The type of plants that Gregor Mendel used in his experiments.
14. Different forms of a gene
15. The study of heredity.
16. The passing of traits from parent to offspring
17. An observable characteristic that is passed from parent to offspring.
18. How a trait appears, or is expressed.

1. When the two alleles in the genotype are different.
2. Pairs of chromosomes that have the same genes for the same traits arranged in the same order.
4. A genetic factor that blocks the presence of another factor.
6. This type of plant is produced by crossing two true breeding plants with opposite traits.
8. This type of plant will always produce the same traits in its offspring when self-pollination occurs.
9. When pollen from one plant lands on the pistil of a different plant, causing reproduction.
10. The two alleles that control the expression of the phenotype.
11. The scientist that is recognized as the father of genetics.
