Crosses involving one gene or trait are called monohybrid crosses.

"Yy" typically refers to a genetic code for a specific trait, where "Y" represents a dominant allele and "y" represents a recessive allele. In terms of individuals, the presence of "Yy" would mean that they have one dominant allele and one recessive allele for that particular trait.
A monohybrid trait refers to the inheritance of one specific trait controlled by a single gene. It involves the study of how a particular trait is passed down from one generation to the next, focusing on one specific gene pair and the variations of that gene that can be inherited.
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
monohybrid cross
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
