Which law is demonstrated by Mendel's dihybrid cross?

When a tall plant with rounded seeds $(TTRR)$ is crossed with a dwarf plant with wrinkled seeds $(ttrr)$,the ${F_1}$ generation consists of tall plants with rounded seeds. How many types of gametes will an ${F_1}$ plant produce?

The law of dihybrid cross proves which of the following?

In a dihybrid cross between $AABB$ and $aabb$,the $F_2$ generation produces offspring with genotypes $AABB$,$AABb$,$AaBB$,and $AaBb$. What will be their phenotypic ratio?

Analyze the given Punnett square. If yellow and round seed alleles are dominant over green and wrinkled seed alleles,which plant will the seeds produced by the plant of genotype $G$ resemble?

In Mendel's dihybrid cross experiment,how many types of genotypes are obtained in the $F_2$ generation?
