Define the term: Filial progeny / $F_{1}$ generation.

If a cross is made between $AA$ and $aa$,the nature of ${F_1}$ progeny will be

If a homozygous red-flowered plant (dominant) is crossed with a white-flowered plant (recessive),the offspring will be:

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

The percentage of heterozygous individuals obtained in $F_2$ generation from selfing the plants with genotype $Rr$ would be

If the genotype of an offspring is $TT$,determine the number of possible gamete types produced by it.
