Step 1
- Allele: Different forms of a gene for the same trait. This matches with option B. - Homozygous: A genotype made of the same alleles; also known as a purebred. This matches with option A. - Dominant: The version of a gene that is always expressed when present. Show more…

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

Match the following terms to the appropriate statement: A. Simple Mendelian inheritance B. Incomplete dominance C. Codominance D. Polygenic inheritance E. Pleiotropy Both alleles are expressed at equal levels and if present together are expressed simultaneously. The presence of the dominant allele masks the effect of the recessive allele Need two copies of the dominant allele to show dominant phenotype and one copy of the allele shows half the phenotype Single gene affects multiple traits More than one gene affects one trait

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.
