1 Self-Quiz 1. In a monohybrid cross, what offspring will result from 2 heterozygotes? 2. If an individual heterozygous for a single trait is test crossed, what offspring will result? 3. In a dihybrid cross, what offspring will result from 2 fully heterozygous plants? 4. If an individual heterozygous for two traits is test crossed, what offspring will result? Self-Quiz 5. Is the following genetic disorder caused by a dominant allele or a recessive allele? How do you know? Label the genotypes. Overview: Mendelian Genetics • Ch. 11: Mendelian Patterns of Inheritance – Multiple allelic traits – Incomplete dominance – Pleiotropy – Polygenic inheritance – X-linked inheritance Multiple Alleles • > 2 alleles for a trait – E.g., I A , I B , & i • Codominance – Heterozygotes ( ) express both alleles Assignment 1 • Think, Pair, Share • Topic: A woman with type AB blood has children with a man with type O blood. – What are the genotypes of the parents? – What are the gametes of the parents? – Cross with a Punnett square. – What blood types of the children are likely? Incomplete Dominance • Incomplete dominance – Recessive allele not completely masked – 1:2:1 F 2 phenotypic ratio • Incomplete penetrance – E.g., polydactyly – E.g., hereditary spherocystosis Assignment 2 • Think, Pair, Share • Topic: In snapdragons, tall
