12. The set of alleles an organism has in its chromosomes.
13. An allele that can be masked by the dominant allele.
14. When an individual has two of the same allele.
15. The intentional breeding of two individuals to combine their genes

1. The first set of parents used when performing a cross.
2. The passing on of traits from one generation to the next.
3. When an individual has two different alleles for the same gene.
5. The offspring resulting from a cross between two individuals from the F1 generation.
6. The observable traits of an organism.
