Genetics is a tough subject, and to make this test even tougher, it poses a double challenge. First, unscramble the following letter combinations to disclose four important genetic terms, then match them with their appropriate definitions.
1. An individual's full complement of genes, half inherited from the sire and half from the dam, some expressed and some not apparent.
2. Having a matched pair of genes-either two dominants or two recessives-for a single trait.
3. The expression of genes that can be readily observed, such as color, conformation and gaits.
4. Having a mixed pair of genes for a single trait, one dominant, one recessive; though the dominant gene is expressed in the individual, the recessive gene is just as likely to be passed off to the offspring.
