Vedclass · Answer

(B) Statement $I$ is true: $A$ dominant allele masks the expression of a recessive allele in a heterozygous condition.Statement $II$ is false: $A$ recessive allele is not 'weaker'; it is simply a variant that does not express its phenotype in the presence of a dominant allele.Statement $III$ is true: $A$ recessive allele does not express its phenotype in the presence of a dominant allele.Statement $IV$ is false: $A$ dominant allele is not always 'better'. For example,many genetic disorders are caused by dominant alleles (e.g.,Huntington's disease).Therefore,statements $II$ and $IV$ are false.
