Dihybrid Cross Punnett Squares

How often do you find a science worksheet that comes with separate teacher's instructions? Here is one of those rare instances. Goals and objectives, materials, and evaluation guidelines precede the actual assignment. Biology leaners...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

The topics in the previous video about dominant and recessive traits are continued here as Sal Khan explains incomplete dominance, the randomness of genotypes and phenotypes, and covers how to calculate probabilities using Punnett...

Introduce young biologists to monohybrid crosses and simple Punnett Squares. It includes explanations of dominant versus recessive and genotype versus phenotype by exploring different genetic combinations of guinea pigs. 

Video tutorial investigates how to use Punnett squares to calculate probabilities of different phenotypes. Includes worked examples of dihybrid crosses, independent assortment, incomplete dominance, codominance, and multiple alleles....

Have fun learning how to use Punnett squares to calculate probabilities of different phenotypes. Provides examples of dihybrid crosses. independent assortment, incomplete dominance, codominance, and multiple alleles. [25:15]

Show learners how to apply genotypes of parents to a Punnett square to determine potential genotypes and phenotypes of offspring with a video that explores monohybrid crosses and then complete a dihybrid cross as well. 

A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...
