Punnett Squares E-Lesson created by Ms. Saleh
This e-Lesson will be presented as part of the class lecture. Pay close attention to how to write the genotype structure of homozygous and heterozygous as well as dominant and recessive. You should know how and when to write the genotype for heterozygous, homozygous dominant, and homozygous recessive. With this information, you should be able to determine resulting genotypes and phenotypes, as well as their ratios. Make sure you go through the entire presentation as the explanations are presented first, followed by an assessment portion.

Monohybrid Crosses
This website offers additional instruction on how to set up monohybrid crosses (which is the cross for one trait). If you’re still a bit confused after viewing the e-Lesson and the class lecture, this website may be helpful in breaking down the information for you. Again, after viewing this website, you should know how and when to write the genotype for heterozygous, homozygous dominant, and homozygous recessive. With this information, you should be able to determine resulting genotypes and phenotypes, as well as their ratios.

Dihybrid Crosses
This website offers additional instruction on how to set up dihybrid crosses (which is the cross for two traits). If you’re still a bit confused after the class lecture, this website may be helpful in breaking down the information for you. Again, after viewing this website, you should know how and when to write the genotype for heterozygous, homozygous dominant, and homozygous recessive for each trait. With this information, you should be able to determine resulting genotypes and phenotypes, as well as their ratios.
