Genetics

2. When the 2 genes in a pair are different
6. When the 2 genes in a pair are identical
8. Genes produce a trait somewhere in between the traits of the 2 parents
10. 1 from each parent
12. One of the forms of a gene that controls a particular trait. Most traits are determined by 2
13. The effect caused by a particular set of genes. What is physically seen.
15. Dominant gene is expressed, unless not present, then recessive gene is expressed

1. A sequence of DNA that codes for a specific protein. Located on the chromosome.
3. The genes responsible for a specific trait. What you cannot see.
4. The phenotype of this gene is only present when the dominant gene in the allele is
5. Structures that carry the genetic information in the form of DNA molecules.
7. A gene that always shows itself. The presence of this type of gene will mask the other
9. A characteristic of a species determined by specific genes.
11. in the allele.
14. A type of square chart that predicts the chances of offspring inheriting a particular trait from their
