Biology Keystone Exam Assessment Anchors:
BIO.B.2: Genetics
BIO.B.2.1: Compare Mendelian and non-Mendelian patterns of inheritance.
BIO.B.2.1.1: Describe and/or predict observed patterns of inheritance (i.e., dominant, recessive, co-dominance, incomplete dominance, sex-linked, polygenic, and multiple alleles).
BIO.B.2.1.2: Describe processes that can alter composition or number of chromosomes (i.e., crossing-over, nondisjunction, duplication, translocation, deletion, insertion, and inversion).
BIO.B.2.2: Explain the process of protein synthesis (i.e., transcription, translation, and protein modification).
BIO.B.2.2.1: Describe how the processes of transcription and translation are similar in all organisms.
BIO.B.2.2.2: Describe the role of ribosomes, endoplasmic reticulum, Golgi apparatus, and nucleus in the production of specific types of proteins.
BIO.B.2.3: Explain how genetic information is expressed.
BIO.B.2.3.1: Describe how genetic mutations alter the DNA sequence and may or may not affect phenotype (e.g., silent, nonsense, frameshift, missense).
BIO.B.2.4: Apply scientific thinking, processes, tools, and technologies in the study of genetics.
BIO.B.2.4.1: Explain how genetic engineering has impacted the fields of medicine, forensics, and agriculture (e.g., selective breeding, gene splicing, cloning, genetically modified organisms, gene therapy).

CRSD Videocast 7.aviGenetics
This video, created by Meghan Vierick and the Council Rock staff, reviews information about Mendelian Genetics, non-Mendelian Genetics, sex-linked traits, and genetic engineering.
CRSD Videocast 6.aviDNA and its Processes
This podcast was created by Meghan Vierick and the Council Rock staff to review the processes involved in DNA replication, protein synthesis, and genetic mutations.
Protein Synthesis with the Amoeba Sisters
In this video, the Amoeba Sisters explore the steps of transcription and translation in protein synthesis. This video explains several reasons why proteins are so important before explaining the roles of mRNA, rRNA, and tRNA in the steps of protein synthesis. Vocabulary in this video includes DNA, mRNA, rRNA, and tRNA. This video mentions that proteins can be made of 1 or more polypeptide chains and that proteins typically experience folding and other modifications (to be functional proteins.) Codons and the amino acids they code for is represented by standard charts.
DNA, Chromosomes, Genes, and Traits with the Amoeba Sisters
In this video, the Amoeba Sister explore DNA structure/function, chromosomes, genes, and traits and how this relates to heredity. This video covers a review of traits, DNA structures, genes, and chromosomes.
Alleles and Genes
Join the Amoeba Sisters as they discuss the terms "gene" and "allele" in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity. Note: as mentioned throughout video, the ability to taste PTC may be more complex than a single gene trait.
Monohybrid Crosses with the Amoeba Sisters
Learn how to use a Punnett square to solve a Mendelian monohybrid cross with one of the Amoeba Sister's favorite classroom pets: hairless guinea pigs.
Multiple Alleles with the Amoeba Sisters
In this video, the Amoeba Sisters demonstrate how to set up and solve a genetic problem involving multiple alleles using ABO blood types as an example.
Incomplete Dominance, Codominance, Polygenic Traits, and Epistasis with the Amoeba Sisters
In this video, the Amoeba Sisters discover more types of non-Mendelian inheritance such as incomplete dominance, codominance, polygenic traits and epistasis.
Sex-Linked Traits with the Amoeba Sisters
This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes).
Dihybrid Crosses with the Amoeba Sisters
In this video, the Amoeba Sisters demonstrate how to set up and solve a 16 square Punnett square. The example solves a two trait (two factor) test cross which can then be useful for solving a dihybrid cross.
Pedigrees with the Amoeba Sisters
The Amoeba Sisters explore autosomal recessive trait and X-linked recessive trait tracking in pedigrees in this video.
Different Blood Types in Humans
In this Amoeba Sisters short, the Amoeba Sisters tell the difference among human blood types A, B, O, and AB blood types. Video mentions antigens and antibodies.
