Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can prevent the allele from being expressed in a pair of genes heterozygous 3. the genes present in an organism homozygous 4. a pair of non-identical genes that influence a trait in different ways dominant 5. a pair of genes that are identical in the way they influence a trait allele 6. offspring from a cross between parents; has different phenotypes for a specific trait

Match the following to the proper definition: Allele An organisms physical appearance 2. Two different alleles for a particular trait Homozygous 3. Will be expressed if paired with a recessive allele Heterozygous Two Identical alleles for a particular trait Genotype organism's genetic make-up or complete set of alleles Phenotype 6. Will only be expressed If two copies of the allele are present Dominant 7. Different forms of the same gene Recessive

Link each term with the correct definition. GENOTYPE $\quad$ 1. An individual that carries one copy each of two different alleles (for example, an Aa individual or an $I B$ individual). $\begin{array}{l}\text { PHENOTYPE } & \text { 2. An individual that carries two copies of the same }\end{array}$ allele (for example, an $A A, a a,$ or $\|$ individual). HETEROZYGOTE $\quad$ 3. An allele that does not affect the phenotype when paired with a dominant allele in a heterozygote. HOMOZYGOTE $\quad 4$. The genetic makeup of an individual; more specifically, the two alleles of a given gene that affect a specific genetic trait in a given individual. DOMINANT $\quad 5$. The specific version of a genetic trait that is displayed by a given individual. RECESSIVE $\quad$ 6. The allele that controls the phenotype when paired with a different allele in a heterozygote individual.
Match the following terms and definitions. 1. cross-breeding; a method that unionizes gametes of differing genes to create a new individual recombinant DNA 2. cultured DNA molecules from different biological sources hybridization 3. a process of breeding organisms because of their specific traits selective breeding
