The capital letter in a punnet square represents the dominant allele, and the lowercase letter represents the recessive allele. The **dominant trait** will always show up when it is present. The **recessive trait** is hidden when the dominant is present. **Co dominance** is when both alleles are dominant or recessive because they can't overpower each other so they mix together. **Incomplete dominance** is when the dominant allele is weak and the recessive mixes with it.

What is sexual and asexual reproduction? **Sexual reproduction** is when to cells or organisms join together to produce offspring, and includes two parents.
 * Asexual reproduction** is when one cell or organism can reproduce alone and only involves one parent.

Why are genes important? What is selective breeding? What are the different types of selective breeding?
 * Genes** control the traits that are expressed in an organism. They come in pairs, so the offspring will inherit one of the genes from each parent.
 * Selective breeding**- when humans use natural genetic patterns that occur in plants and animals to pass desired traits to the next generation
 * Inbreeding**- a type of sexual reproduction that can cause birth defects because the probability of inheriting two recessive genes is greater
 * Hybridization**- includes sexual reproduction and crosses individuals with desired traits in order to produce organisms with both of the desired traits
 * Genetic Engineering**- when a bit of genetic material is removed from an organism and inserted into another
 * Cloning**- when a single cell from an organism is used to produce an organism with the same genetic information
