Lesson Plan GRADE 9 SCIENCE HEREDITY: INHERITANCE AND VARIATION

The lesson plan is for a 9th grade science class on heredity and the multiple allele system of determining blood type. The objectives are for students to define multiple alleles, enumerate possible gene pairs for blood types, and identify phenotypes using a Punnett square. Students will review codominance, define and give examples of multiple alleles, and use a Punnett square...

The lesson plan is for a 9th grade science class on heredity and the multiple allele system of determining blood type. The objectives are for students to define multiple alleles, enumerate possible gene pairs for blood types, and identify phenotypes using a Punnett square. Students will review codominance, define and give examples of multiple alleles, and use a Punnett square activity to determine unknown parent blood types. The teacher will explain multiple alleles, codominance, and how the three alleles (A, B, and O) control the four blood types.
