When a tall and red-flowered individual is crossed with a dwarf and white-flowered individual,the phenotype in the progeny is dwarf and white. What will be the genotype of the tall and red-flowered individual?

In a cross performed between parents considering two contrasting characters yellow round and green wrinkled seeds. In the $F_2$ generation progeny,the ratio of yellow and green will be . . . . . . .

Pure homozygous offspring in a dihybrid cross in the ${F_2}$ generation will be:

In rabbits,black skin $(B)$ is dominant over brown skin $(b)$ and short hair $(S)$ is dominant over long hair $(s)$. $A$ homozygous black,short-haired male is crossed with a homozygous brown,long-haired female. All $F_1$ offspring are heterozygous black,short-haired. If the $F_1$ male is crossed with an $F_1$ female,what is the percentage of homozygous black,short-haired offspring in the $F_2$ generation (in $\%$)?

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:

The probability of the genotype $TTrr$ in the $F_2$ generation of a dihybrid cross is:
