Determine the number of possible gametes produced by an organism with the genotype $AaBbCc$.

$A$ diploid organism is heterozygous for $5$ loci and homozygous for $2$ loci,how many types of gametes can be produced?

Read the following statements.
Statement $I$: In a typical test cross, an organism showing a dominant phenotype is crossed with the recessive parent.
Statement $II$: The ratio of organisms showing dominant and recessive traits in $F_1$ generation of a test cross indicates that the organism with unknown genotype is homozygous dominant.
Choose the correct option.
