Unit 3: MENDELIAN GENETICS

- LP 3.1: I can construct a scientifically accurate claim to identify the patterns in the relationship between phenotype and genotype.

- LP 3.2: I can use patterns in a monohybrid punnett square as evidence to support a claim that explains the inheritance of traits.

- LP 3.3: I can analyze and interpret data sets using statistics and probability to identify the possible outcomes (effects) of complex punnett squares.

- LP 3.4: I can analyze data in order to make a claim to explain the patterns in the inheritance of traits through the construction of a pedigree.

- LP 3.5: I can use evidence and scientific theories to explain the effect of the environment on the expression of genes and variation in phenotypes.

STUDENTS WILL:

EXPLORE THE FOLLOWING SCIENCE AND ENGINEERING PRACTICES:

-Analyzing and Interpreting Data


HAVE DISCOURSE ON THE FOLLOWING DISCIPLINARY CORE IDEAS:

LS1.A: Structure and Function
All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins. (secondary to HS-LS3-1) (Note: This Disciplinary Core Idea is also addressed by HS-LS1-1.)

LS3.A: Inheritance of Traits
Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species’ characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function. (HS-LS3-1)

LS3.B: Variation of Traits
In sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation. Environmental factors can also cause mutations in genes, and viable mutations are inherited. (HS-LS3-2)

Environmental factors also affect expression of traits, and hence affect the probability of occurrences of traits in a population. Thus the variation and distribution of traits observed depends on both genetic and environmental factors. (HS-LS3-2),(HS-LS3-3)
