Vedclass · Answer

(C) Step $1$: Statement $I$ is true. $A$ test cross is defined as the cross between an individual with a dominant phenotype (but unknown genotype) and a homozygous recessive parent to determine the genotype of the dominant individual.Step $2$: Statement $II$ is false. In a test cross, if the unknown organism is homozygous dominant $(AA)$, all offspring will show the dominant trait $(Aa)$. If the unknown organism is heterozygous $(Aa)$, the offspring ratio will be $1:1$ (dominant to recessive). The ratio does not indicate the organism is homozygous dominant; rather, a $1:1$ ratio indicates it is heterozygous, and a $100\%$ dominant ratio indicates it is homozygous dominant.Step $3$: Therefore, Statement $I$ is true and Statement $II$ is false.
