6. Physical appearance or trait that is visible.

7. Reproductive process that involves two parents who combine their genetic material through fertilization to produce a new organism, which differs from both parents. (2 Words)

9. The process where the egg & sperm fuse to form a new individual in sexual reproduction.

11. A segment of DNA that carries the genetic information that controls a specific trait.

14. Reproductive process that involves only one parent and produces offspring that are identical to the parent. (No variation!) (2 Words)

16. Production of new individuals to ensure the survival of a species.

17. A characteristic that an organism can pass on to its offspring through its genes.

18. Non-parasitic flatworm that can reproduce sexually or through regeneration.

19. Normal differences that occur between individuals in a population caused by genetic differences.

20. Rod-shaped structures in the nucleus of a cell that are made up of DNA which carries the information that is passed from parents to offspring.

1. Gene combination or alleles that determine a trait.

2. Structure that makes up chromosomes. Made up of genes that carry information about an organism that controls inherited characteristics. (3 Words)

3. The Father of Genetics. His famous pea plant experiments, conducted from 1856-1863, helped to illustrate and establish the laws of inheritance. (2 Words)

4. Weak form of a gene that is masked when a dominant allele is present… represented by a lower case letter. (2 Words)

5. Discovered chromosomes while observing the process of cell division. (2 Words)

8. Strong form of a gene whose trait always shows up in the organism when the allele is present… represented by a capital letter. (2 Words)

10. Type of asexual reproduction where lost or damaged body part grows back.

12. The different forms of a gene in a gene pair.

13. A graphic tool used to predict the probability of genotypes (allele pairs) in an offspring. (2 Words)

15. Type of asexual reproduction where a bud grows and breaks off the parent organism resulting in an exact duplicate.
