Mr. Andersen explains the concepts of genetic recombination and gene mapping. [9:43]

Learn about the gene as a stretch of DNA on a chromosome. Also find out about alleles as versions or sequence variants of a gene. [8:17]

An explanation of what DNA and genes are. Includes video and text. [1:13]

A gene as a stretch of DNA on a chromosome. Alleles as versions (sequence variants) of a gene. [8:18]

Understand how a gene is a stretch of DNA on a chromosome. Find out about alleles in their role as versions sequence variants of a gene. [8:18]

Find out how chromosomes and genes are passed down from parent to child in this video lecture. Understand how you get one set of chromosomes for your mother and one set of chromosomes from your father. [4:20]

Find out about the basics of cells, chromosomes, and the genes contained in your DNA. [4:26]

This lesson will discuss how scientists use dominant and recessive genes to predict inherited traits of offspring.

Sometimes trailblazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again....

This lesson will give examples of disorders that are linked to genes on the X chromosome. It is 2 of 5 in the series titled "X-Linked Traits and Disorders."

Paul Andersen explains aspects of genetics that were not covered by Gregor Mendel. He begins with the following topics; incomplete dominance, codominance, epistasis, multiple alleles, and multiple genes. He then explains how linked genes...

See how an X or Y chromosome carried by a sperm cell, determines the sex of the offspring in this video. [5:52]

An introduction to heredity. Understand important terms in genetics like dominant and recessive traits, and heterozygous and homozygous genotypes. [17:27]

In this video students will learn that a mutation is a change in the genetic structure through deletion, insertion, or duplication. They will also learn the significance of the gene and chromosome mutations. Teachers can visit Amoeba...

In this video you will learn the process of genetics and how you receive your particular genetic traits.

Learn about the difference between the X and Y chromosome in this Khan Academy video. Video discusses sex-linked genes that cause color blindness and hemophilia on the X chromosome. [14:18]
