Ch 14: Genetics - Principles of Heredity: Tutoring Solution

About This Chapter

The Genetics: Principles of Heredity chapter of this High School Biology Tutoring Solution is a flexible and affordable path to learning about genetics and principles of heredity. These simple and fun video lessons are each about five minutes long and they teach all of the heredity principles required in a typical high school biology course.

How it works:

  • Begin your assignment or other high school biology work.
  • Identify the genetics and heredity principles concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our high school biology tutoring solution will benefit any student who is trying to learn genetics and principles of heredity and earn better grades. This resource can help students including those who:

  • Struggle with understanding properties of alleles, Mendel's First and Second Laws, chromosomal linkage, crossing over or any other genetics and principles of heredity topic.
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their genetics and principles of heredity unit
  • Cope with ADD or ADHD
  • Want to get ahead in high school biology
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning genetics and principles of heredity simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn genetics and principles of heredity on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • List the properties of alleles.
  • Understand Mendel's first and second laws and discuss their applications.
  • Discuss the exceptions to simple dominance, such as codominance and incomplete dominance.
  • Learn about the exceptions to independent assortment, such as sex-linked and sex-limited traits.
  • Explain how chromosomal linkage and crossing over can affect inheritance.
  • Describe how model organisms can be used to understand human genetics.

Genetics: Heredity, Traits & Chromosomes

1. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

Properties of Alleles

2. Properties of Alleles

What is a dominant phenotype and how will it affect Adrian's flying hamster research? Tune in as he studies homozygous and heterozygous genotypes and the phenotypes they produce.

Mendel's First Law: The Law of Segregation

3. Mendel's First Law: The Law of Segregation

Breaking up is a hard thing to do, but homologous chromosomes always go their separate way. What effect does chromosome segregation have on genetics? We look once more to Adrian's flying hamsters for answers.

Application of Mendel's First Law

4. Application of Mendel's First Law

Hollywood Squares? No, it's Punnett Squares! Those wacky diagrams are a geneticist's best friend. See how they turn geneticists into soothsayers, predicting the genotypic and phenotypic future.

Mendel's Second Law: The Law of Independent Assortment

5. Mendel's Second Law: The Law of Independent Assortment

Understanding how Mendel's law of independent assortment describes inheritance of genes is as easy as flipping a coin. Grab a few coins, cue up the video and see how.

Mendel's Dihybrid Cross Example: Practice & Ratio

6. Mendel's Dihybrid Cross Example: Practice & Ratio

Oh no! Twice the genes and sixteen genotypes - a dihybrid cross seems overwhelming to understand. Never fear though, Punnett squares will save the day!

Exceptions to Simple Dominance: Codominance and Incomplete Dominance

7. Exceptions to Simple Dominance: Codominance and Incomplete Dominance

Have you ever wondered what it means if someone is a universal donor or acceptor of blood? See how genetic interactions play a key role in this trait.

Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

8. Exceptions to Independent Assortment: Sex-Linked and Sex-Limited Traits

More men are color blind compared women. But often, not every brother, cousin or uncle in a family tree is color blind. Why not? How can genetics explain this seemingly complex inheritance pattern?

Crossing Over & Gene Linkage: Definition, Importance & Results

9. Crossing Over & Gene Linkage: Definition, Importance & Results

During this latest development of his flying hamster experiments, Adrian must learn about linked genes and recombinant chromosomes to unlock the mystery of the fire-breathing hamster. In this lesson, you'll look at another exception to Mendel's law of independent assortment.

Human Genetics: Multifactorial Traits & Model Organisms

10. Human Genetics: Multifactorial Traits & Model Organisms

How do we study human genetics when most traits arise from multiple genes? It's certainly more complicated that drawing a simple Punnett square. Never fear, for model organisms are here!

Genetic Structure of Human Populations: Definition & Concept

11. Genetic Structure of Human Populations: Definition & Concept

Human beings are extremely diverse in appearance and susceptibility to diseases such as cancer, diabetes and obesity -- yet our genomes our 99.9% identical. How are we so different if our genome says we are nearly all the same? Read on to learn more.

Pleiotropy: Definition & Examples

12. Pleiotropy: Definition & Examples

There are many different mutations that occur during growth in organisms. Many times, these mutations can be passed on and will occur in such a way as to be beneficial to the organism. Sometimes, they are not. We will be looking at one such type of mutation here.

Quantitative Trait: Definition & Concept

13. Quantitative Trait: Definition & Concept

What determines how tall a person will be? Is it the genes a person carries or is it the environment that determines how tall a person may grow? We will answer these questions as we explore quantitative traits.

Recessive Trait: Definition & Example

14. Recessive Trait: Definition & Example

Can you bend your thumb backwards like a hitch-hiker? Do you have small, attached earlobes? Are your eyes blue? If you answered yes to any one of these, then you have a recessive trait. Learn what recessive traits are in this lesson.

Allele Frequency: Definition, Calculation & Example

15. Allele Frequency: Definition, Calculation & Example

This lesson will discuss what an allele is and how its frequency is calculated in a population. The Hardy-Weinberg principle will also be explained mathematically in this lesson with practical examples.
