Biology

In the context of genetics and alleles determining a plant's phenotype, when one allele is dominant, it typically masks the expression of the recessive allele.

For example, in pea plants, if the allele for tall height (T) is dominant over the allele for short height (t), a plant with a genotype of Tt will have a tall phenotype.

The phenotype is, in a sense, the result of the combination of alleles, and the presence of a dominant allele often means the recessive allele's effect on the phenotype is not seen.

Option B is incorrect because there is a clear pattern of inheritance. Mendelian genetics shows that alleles follow specific laws such...
