A common test to find the genotype of a hybrid is by:
  1. crossing of one $F_2$ progeny with female parent
  2. studying the sexual behaviour of $\mathrm{F}_1$ progenies
  3. crossing of one $F_1$ progeny with male parent
  4. crossing of one $\mathrm{F}_2$ progeny with male parent.

Solution

A common test to find the genotype of a hybrid is a test cross. Here, $\mathrm{F}_1$ hybrids are crossed with the recessive parent. Phenotypic ratios of $1: 1$ confirm that the $\mathrm{F}_1$ hybrid is heterozygous. Related Theory
