Appearance of new combinations in $F_2$ generation of a dihybrid cross proves the law of . . . . . . .

In Mendel's dihybrid cross experiment,when $F_1$ generation plants are self-pollinated,what is the proportion of each type of gamete produced (in $\%$)?

When $AABbcc$ is crossed with $AaBbCc$,what is the probability of obtaining an offspring with the genotype $AaBbcc$?

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

In plants,red color $(R)$ is dominant over yellow $(r)$ and tallness $(T)$ is dominant over dwarfness $(t)$. If a plant with genotype $RRTt$ is crossed with a plant with genotype $rrtt$,what will be the result?

How many different types of gametes can be produced by the $F_1$ progeny resulting from the cross $AA BB CC \times aa bb cc$?
