Question

Explain why a recessive allele is unable to express itself in a heterozygous state

Answer 1

here tall character is dominant so it suppress the recessive gene ..
a recessive allele is unable to express itself ..acc to mendel's law of dominance:factors occur in pairs .in a dissimilar pair of factors one member of the pair dominates the other .

Answer 2

Recessive and dominant alleles follow simple Mendelian genetics which states that recessive alleles will always be masked or covered in the presence of dominant alleles.

A heterozygous state means that there is one dominant allele and one recessive allele. Following simple Mendelian genetics, because there is a dominant allele present, the recessive allele is masked. This means that only the dominant allele will be seen.
