Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why classification can have major changes due to DNA and cell
Punnett Squares - Basic Introduction
"This biology video tutorial provides a basic introduction into punnett squares. It explains how to do a monohybrid cross and a dihybrid cross. It discusses the difference between the dominant allele and the recessive allele. It also covers terms such homozygous dominant, heterozygous, and homozygous recessive. It contains plenty of examples and practice problems that explains how to calculate the probability of an offspring with certain characteristics such as eye color. Finally, it also explains how to calculate the genotype ratio as well as the phenotype ratio. It also includes an example of incomplete dominace with white, red, and pink flowers."
