Design an experiment to determine whether the pink flower of petunia plants results from incomplete dominance.

To cross petunia plants/lines with pink flowers (F1) which were obtained by crossing plants with red and white flowers (parental generation). The presence of petunia plants with red or white flowers in F2 would evidence that this trait is under incomplete dominance.

Explanation:

Incomplete dominance is a type of relationship in which both alleles are expressed in heterozygous individuals, thereby resulting in a new phenotype. This type of allelic interaction is commonly referred to as 'the dilution of the dominant allele' in heterozygous individuals. Moreover, codominance refers to a type of allele relationship in which both alleles are expressed to an equal degree in heterozygous individuals.

the answer would be d

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
