Biology Unit 4 Genetics Learning Objectives
Genetics/Science Content Objectives
4.1.1 Analyze genetic patterns to determine dominance or recessive inheritance patterns.
4.1.2 Summarize examples of dominant, recessive and sex linked disorders.
4.1.3 Construct human pedigrees from genetic information.
4.1.4 Explain the structure, composition and function of chromosomes in living things.
4.1.5 Recognize and summarize the stages of meiosis and the final outcome.
4.1.6 Explain the reduction in chromosome number that occurs during meiosis.
4.1.7 Describe how crossing over is related to variation in offspring.
4.1.8 Compare and contrast mitosis and meiosis.
4.1.9 Distinguish normal karyotypes from those with abnormal numbers of chromosomes.
4.1.10 Relate the effect of nondisjunction to Down syndrome and other abnormal
chromosome numbers.
4.1.11 Explain the significance of Mendel’s experiments to the study of genetics.
4.1.12 Predict the possible offspring from a monoybrid and dihybrid crosses using Punnett
squares. Derive the genotypic and phenotype ratios.
4.1.13 Distinguish between various complex inheritance patterns (incomplete dominance, codominance, sex linked, and sex influenced traits).
College Readiness Skills Objectives
4.2.1 Create a model to illustrate the inheritance of genetic traits.
20E.1 Select a simple hypothesis, prediction, or conclusion that is supported by a data
presentation or model.
24E.2 Identify key issues or assumptions in a model.
16I.3 Find basic information in a brief body of text.
16I.4 Determine how the value of one variable changes as the value of another variable
changes in a simple data presentation.
20I.3 Translate information into a table, graph or diagram.
