How many phenotypes can be obtained if a pea plant $(RrTt)$ is crossed with another pea plant with the same genotype?

In an experiment on pea plant,pure plants with yellow round seeds $(YYRR)$ were crossed with plants producing green wrinkled seeds $(yyrr)$. What will be the phenotypic ratio of $F_1$ progeny?

In the $F_{2}$ generation of a Mendelian dihybrid cross $(TTRR \times ttrr)$,which of the following statements is correct?

Probability of genotype $TTrr$ in $F_{2}$-generation of a dihybrid cross is

In a dihybrid cross experiment,what is the phenotypic ratio obtained from the test cross of $F_1$ generation plants?

Heterozygous round and yellow seeded pea plants were selfed and a total of $800$ seeds were collected. What is the total number of seeds with the first dominant trait (round) and the second recessive trait (green)?
