A. Dominance is an autonomous feature of a gene or the product that it has information for.
B. A single gene product may produce only one effect.
C. Blood group AB is an example of codominance.
DMore than two alleles exist in a population for a single gene.
Options:
Answer:
D
Solution:
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, in case more than one phenotype is influenced by the same gene. Occasionally, a single gene product may produce more than one effect.
