In this biology worksheet, 9th graders identify which seed color is dominant in the given chart and explain why it is. Then they create a Punnett square showing the alleles of the parent plants and first generation of offspring.

In this biology learning exercise, 9th graders describe how two alleles can produce three phenotypes. Then they create a Punnett square showing the possible offspring of red and white cattle. Students also determine the genotypes and...

In this biology activity, students use the information given to complete each of the questions. They indicate whether each genotype is heterozygous or homozygous. Students also complete the Punnett square to illustrate the possibilities...

In this biology worksheet, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the daughter is...

In this biology worksheet, students use the information given about genetics and Sponge Bob to complete each section of the sheet. They identify and explain incomplete dominance and use it to help them complete the questions that follow.
