Some heterozygous alleles create variations in expression so that there is not a clear dominant or recessive allele. question 1 options: true false

The given statement is true.

It can be explained with the help of a phenomenon termed as codominance.

It is a type of allelic interaction in which both the alleles are equally expressive in a heterozygous condition.

For example, in humans, allele A and B express equally to produce the phenotype blood group AB.

The other example may include the fur color of the cattle in which red and white hairs express equally and produce red and white patches.
