How to use or fill out the Dihybrid Cross Worksheet online
Filling out the Dihybrid Cross Worksheet online is a straightforward process. This guide will provide you with clear instructions on how to complete each section effectively, ensuring that you accurately represent your genetic crosses.
Follow the steps to complete your Dihybrid Cross Worksheet online.
- Click ‘Get Form’ button to obtain the form and access it in the online editor.
- Begin with the first section where you will enter your name, class, and date. These fields help personalize the worksheet for your records.
- In the section titled 'P Generation genotypes,' input the genotypes for the parent plants of your first cross, using the format provided in the example.
- Next, complete the 'Possible gametes' field. List the gametes that each parent can produce based on their genotypes.
- Draw the Punnett square to represent the cross. Based on the gametes, fill in each cell with the resulting genotypes.
- Calculate the genotypic ratio by counting the occurrence of each genotype from your Punnett square.
- Similarly, calculate the phenotypic ratio based on the traits indicated by the genotypes in the completed Punnett square.
- Repeat the previous steps for additional crosses included in the worksheet. Ensure that each cross is filled out accurately in accordance with the genetic principles.
- Once you have completed all sections of the worksheet, review your entries for accuracy.
- You can now save your changes, download a copy, print the worksheet, or share it as needed.

This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort independently into gametes.
