Solution
F1 progeny:
When distinct parents are crossed in a controlled manner, the first generation offspring is called the F1 generation.
It is also called the first filial generation.
The F1 generation always contains two alleles.
One allele is tall and the other is a dwarf.
The tall progeny is present in heterozygous conditions and the tall trait is dominant that expresses itself and suppresses the expression of the short trait.
