Unit Animals at the Cellular Level Lesson Heredity

Unit: Animals at the Cellular Level Lesson: Heredity

� Codominance � Probability � Dominant � Punnett Square � Heritability � Qualitative Trait � Heritability Estimate � Quantitative Trait � Incomplete Dominance � Recessive

� 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

� 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

� 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
