Genetics

5. The observable characteristics or traits of an organism, resulting from the interaction of its genotype with the environment.
7. A segment of DNA that codes for a specific protein or functional RNA.
8. The presence of more than two alleles for a genetic trait within a population, although an individual can only have two of these alleles.
9. Allele: An allele that expresses its phenotype even when only one copy is present in the genotype.
11. The specific location of a gene or DNA sequence on a chromosome.
12. Allele: An allele that only expresses its phenotype when two copies are present in the genotype.

1. The genetic makeup of an organism, represented by the alleles it possesses.
2. Having two identical alleles for a particular gene.
3. A form of gene interaction where one gene masks or modifies the expression of another gene at a different locus.
4. A situation where both alleles in a heterozygous organism contribute equally and visibly to the phenotype.
6. Having two different alleles for a particular gene.
10. Different versions of the same gene, which can result in variations in the trait they control.
