In Mendel's dihybrid cross,what is the probability of obtaining a plant that is heterozygous for both traits (in $/16$)?

How many types of gametes are produced by a dihybrid plant?

Describe the inheritance of two genes.

In a dihybrid cross between individuals with genotypes $TtRr$,if the total number of offspring is $16$,identify the number of individuals with genotypes $TtRr$ and $TtRR$ among them.

In peas,tallness is dominant over dwarfness and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated with a dwarf plant bearing white flowers,the different phenotypic groups were obtained in the progeny in numbers mentioned against them:
Tall,Red $= 138$
Tall,White $= 132$
Dwarf,Red $= 136$
Dwarf,White $= 128$
Mention the genotypes of the two parents and of the four offspring types.

If a plant having yellow and round seeds was crossed with another plant having green and wrinkled seeds,then the $F_{1}$-progeny are in the ratio:
