The correct genotypes of the parents are ggrr for yellow pods with wrinkled seeds and GgRr for <span>heterozygous for green pods with round seeds.
If the heterozygous individuals for both traits express have green pods and round seeds that tells us that these traits are dominant.
In the gross presented below, you can see that the offspring will have 4 different genotypes, all present in an equal percentage:
</span><span>gGrR 25%
</span><span>gGrr </span>25%
<span>ggrR 25%
</span><span>ggrr 25%</span>
Yes, it is possible to develop effective vaccines for any type of viruses. Genetically engineered viruses exhibit similar characteristics to natural viruses.
<h3>What is a virus?</h3>
A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).
A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.
Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.
