The correct answers are:<br /><br />1. $100\%$ of the offspring will show the dominant phenotype.<br />2. None of the offspring will show the recessive phenotype.<br /><br />Explanation:<br />When crossing a homozygous dominant parent (AA) with a heterozygous parent (Aa) for a given trait, the possible genotypes of the offspring are:<br />- 50% AA (homozygous dominant)<br />- 50% Aa (heterozygous)<br /><br />Since the dominant allele (A) masks the effect of the recessive allele (a), all of the offspring will show the dominant phenotype. Therefore, none of the offspring will show the recessive phenotype.
