Standard IV-Objective 2 Heredity

Standard IV: Students will understand that Genetic information coded in DNA is passed from parents to offspring by sexual reproduction. The basic structure of DNA is the same in all-living things. Changes in DNA may alter genetic expression.
Objective 2: Predict and interpret patterns of inheritance in sexually reproducing organisms.

Enduring Understanding: There are predictable patterns of inheritance. Inheritance patterns in sexually reproducing organisms are based on Mendel's laws of segregation and independent assortment. Traits can be dominant, recessive, codominant, sex-linked or have incomplete dominance. Plants and animals have been selectively bred for desired traits.

Essential Questions

1. How does Mendel's law of segregation predict the number of genetic traits passed from the mother and the father?
2. How would Mendel have explained the chances of getting a round seed with a tall plant?
3. Predict the outcome of a cross between a parent with AO blood type and BO blood. Describe the genotypes and phenotypes.
4. How do Mendel's ideas continue to impact the breeding practices of farmers and ranchers?
