Dominance Depends on Gene Product & Phenotype — NEET Biology

📚 Practice Concept
📖 NCERT Source

Therefore, dominance is not an autonomous feature of a gene or the product that it has information for. It depends as much on the gene product and the production of a particular phenotype from this product as it does on the particular phenotype that we choose to examine, in case more than one phenotype is influenced by the same gene.

Evaluate dominance: (1) Dominance depends on gene product and phenotype we examine. (2) Recessive phenotype results when non-functional enzyme produced. (3) Equivalent alleles can produce same genotype despite sequence changes. (4) In starch synthesis, heterozygotes show intermediate grain size if measured. (5) Therefore, dominance is autonomous property of a gene. Which statements are correct?
