What type of gametes will form by genotype RrYy?

In dihybrid cross, the pattern of inheritance represented by the punnett square given below, where yellow $\left(\mathrm{Y}\right)$ is dominant over white $\left(\mathrm{y}\right)$ and round $\left(\mathrm{R}\right)$ is dominant over wrinkled $\left(\mathrm{r}\right)$ seeds

A plant of type $\text{'}\mathrm{H}\text{'}$ will produce seeds with the genotype identical to seeds produced by the plants of

When a true breeding pea plant that has yellow seeds is pollinated by a plant that has green seeds, all the ${\mathrm{F}}_1$ plants have yellow seeds. This means that the allele for yellow is

Or

A character which is expressed in hybrid is called
