Crossing two different types of plants to create a new hybrid is a common technique in agriculture. But what about in the world of genetics? What if you wanted to create a dihybrid cross—two varieties of plants that are not naturally crossed? In this tutorial, we will show you how to do a dihybrid cross in both garden and laboratory settings. By following these steps, you will be able to create new hybrids with greater ease and efficiency.
What is a dihybrid cross?
A dihybrid cross is a cross between two different plant species that results in the production of offspring that are not purebred from either parent. The process of producing these offspring is called hybridization. Dihybrid crosses can be used to create new varieties or to improve the characteristics of existing plants.
How to do a dihybrid cross?
To do a dihybrid cross, you will need:
-Two parental strains of bacteria
-A sterile fifth strain (used for marker purposes only)
-Sterile equipment
-Lab scale agar plates or petri dishes
-Water
-Distilled water (for making adjusted media)
-Trypticase soy broth (TSB) or Geneticin Overnight Agar (GIA)
-DNA isolation kit, such as the DNeasy Blood and Tissue DNA Isolation Kit (#99122) or the QIAamp DNA Mini Kit (#95690)
-Double stranded sequencing primer pairs and reagents, such as the ABI Prism 7700 Sequence Detection System #76015, dNTPs, and DNA ligases
-High performance liquid chromatography (HPLC), such as the Shimadzu LC10A HPLC System with Inline Addition/Subtraction Pump (#HPA018070), to analyze dihybrid crosses

What are the benefits of doing a dihybrid cross?
There are many benefits to doing a dihybrid cross. The most obvious benefit is that you can create new, genetically unique lines of animals. This can be useful if you want to create animals with specific traits, or if you want to study the genetic variability of a population.
Another benefit of doing a dihybrid cross is that you can create animals with interesting personalities. For example, if you cross two different strains of mice, you may end up with mice that are more aggressive or playful.
Finally, doing a dihybrid cross can help you create new lines of crops. For example, by crossing two different types of corn, you may be able to produce a strain that is better resistant to pests or diseases.
What are the risks of doing a dihybrid cross?
There are a few risks associated with doing a dihybrid cross. One risk is that if one parent has a dominant gene, the child will have that gene as well. This can result in health problems or abnormalities. Another risk is that if one of the parents is heterozygous, their child may not be able to inherit both genes and may have some variability in their phenotype (the observable traits of an organism).
Conclusion
Thanks for reading our article on how to do a dihybrid cross. In this article, we will be teaching you everything you need to know about the process of doing a dihybrid cross. We will explain the steps that you need to take in order to ensure that both parents share the same gene set, and we will also give you some tips on how to select the best plants for your dihybrid crossing. Finally, we will provide an example of a dihybrid cross that was successfully produced using our methods. So whether you are new to breeding or have been doing it for years, we hope this article has helped clarify some of the more confusing aspects of dihybrids.
