For example when we cross a red coloured flower (RR) with white coloured flower (rr). After the cross, the gametes produced is (Tt). Hence Tt is the genotype of that trait but the phenotypic is ‘tall’. Complete answer:
WebThis is often known as a dihybrid. It is heterozygous in both genes. Now, what's the phenotype here? Well, we know yellow is dominant, and we know round is dominant. So if we looked at these plants right over here, their peas would still be yellow round, just like this …
