Unit 5 Progress Check FRQ AP Bio presents a comprehensive examination of the fundamental concepts and principles explored in Unit 5 of the Advanced Placement Biology curriculum. This assessment serves as a valuable tool for students to gauge their understanding of the unit’s key topics, including Mendelian genetics, extensions of Mendelian genetics, molecular genetics, and biotechnology.

As students embark on this progress check, they will encounter a series of free-response questions designed to evaluate their ability to analyze, interpret, and apply their knowledge of biological concepts. These questions may require students to draw upon their understanding of genetic inheritance patterns, molecular processes, and the applications of biotechnology in the real world.

Unit 5 Overview: Unit 5 Progress Check Frq Ap Bio

Unit 5 of AP Biology delves into the fundamental principles of genetics, from the classical Mendelian laws to the molecular basis of inheritance. This unit provides a comprehensive understanding of how traits are passed down from one generation to the next, exploring both the basic concepts and their modern-day applications.

Key topics covered in this unit include Mendelian genetics, extensions of Mendelian genetics, molecular genetics, and biotechnology. Through the study of these topics, students will gain a deep understanding of the mechanisms underlying inheritance and the potential applications of genetic technologies.

Mendelian Genetics

Mendelian genetics forms the foundation of our understanding of inheritance. Developed by Gregor Mendel in the mid-19th century, Mendelian principles explain how traits are passed down from parents to offspring through the segregation and independent assortment of alleles.

Dominance, Recessiveness, and Allele Frequency

• Dominance: When one allele masks the expression of another allele in a heterozygous individual.
• Recessiveness: When an allele is only expressed in homozygous individuals.
• Allele Frequency: The proportion of a particular allele in a population.

Types of Genetic Crosses

• Monohybrid Cross: A cross involving a single gene with two alleles.
• Dihybrid Cross: A cross involving two genes, each with two alleles.
• Test Cross: A cross used to determine the genotype of an individual with a dominant phenotype.

Predicting Outcomes of Genetic Crosses

Using Mendelian principles, it is possible to predict the probability of inheriting specific traits based on the genotypes of the parents. This is achieved through the use of Punnett squares and probability calculations.

Extensions of Mendelian Genetics

Mendelian genetics provides a basic framework for understanding inheritance, but there are several extensions that expand on these principles.

Incomplete Dominance and Codominance

• Incomplete Dominance: When neither allele is dominant and the heterozygous individual exhibits a phenotype that is intermediate between the two homozygous phenotypes.
• Codominance: When both alleles are expressed in the heterozygous individual, resulting in a distinct phenotype.

Multiple Alleles and Polygenic Traits

• Multiple Alleles: When a gene has more than two alleles.
• Polygenic Traits: Traits that are influenced by multiple genes, each with small effects.

Sex-Linked Genes, Unit 5 progress check frq ap bio

Sex-linked genes are located on the X or Y chromosomes. Their inheritance patterns differ from autosomal genes due to the presence of only one X chromosome in males.

Molecular Genetics

Molecular genetics explores the molecular basis of inheritance, focusing on the structure and function of DNA and RNA.

Structure and Function of DNA and RNA

• DNA: A double-stranded molecule that carries genetic information.
• RNA: A single-stranded molecule that plays a role in protein synthesis.

Processes of DNA Replication, Transcription, and Translation

• DNA Replication: The process by which DNA makes a copy of itself.
• Transcription: The process by which DNA is used to create RNA.
• Translation: The process by which RNA is used to create proteins.

Types of Mutations

• Point Mutations: Changes in a single nucleotide.
• Insertions and Deletions: Additions or removals of nucleotides.
• Frameshift Mutations: Mutations that alter the reading frame of a gene.

Effects of Mutations

Mutations can have varying effects on gene function, ranging from silent mutations with no effect to mutations that cause genetic disorders.

Biotechnology

Biotechnology utilizes genetic technologies to modify organisms and create products for various applications.

Principles and Applications of Biotechnology

• Genetic Engineering: The process of modifying an organism’s DNA.
• Cloning: The process of creating genetically identical copies of an organism.
• Gene Therapy: The use of genetic technologies to treat diseases.

Ethical Implications of Biotechnology

The use of biotechnology raises ethical concerns related to the potential impact on the environment, human health, and social justice.
