2. Heredity Terms Codominance Probability Dominant Punnett Square
Heritability
Qualitative Trait
Heritability Estimate
Quantitative Trait
Incomplete Dominance
Recessive

3. Estimated Heritability
Probability is the likelihood that a trait will occur in the offspring of two parents with known genetics
Heritability is the proportion of the total variation (genetic and environmental) due to additive gene effects
An approximation of the passing of traits from parents to offspring is called Heritability Estimate

4. The different types of traits
Some traits are controlled by just one pair of genes, and others require several pairs of genes for traits to be included within an animals genetics
Qualitative trait is a trait controlled by one pair of genes
Quantitative Trait is a trait controlled by several pairs of genes
Dominant Trait takes priority of expression
Recessive Trait may be passed on to offspring but rarely expressed, except in certain combinations
Incomplete Dominance occurs when genes or alleles are blended and expressed

5. Punnet Square
The Punnet Square is a technique used for predicting genotypes
It takes the dominant or recessive Traits of each parent and determines what combination of traits their offspring will receive
