State which of the following is not true. 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. D. More than tow alleles exist in a population for a single gene.

Select incorrect statement (A) Linked genes cause absolute lethality (B) Persons affected by PKU do not show mental disorder (C) F_(2) ratio in codominance and incomplete dominance are same, (D) Sex of male Drosophila is dependent on Y- chromosome

For a particular gene that determines the coat color in a diploid organism, there are three different alleles that are codominant. How may different skin colors are possible in such an organism.

Assertion : In a person with AB blood group, the erthrocyes carry both A and B antigenes on their surface. Reason : The allels I^(A) and I^(B) , that produe AB blood group, are codominant and both are expressed.

Assertion : The person heterozygous for sickle- cell trait produces both normal (Hb^(A)) and abnormal haemoglobin (Hb^(S)) . Reason : Huamn normal allele and the sickle allele are codominant.

To allele for pea comb (P) in chickens is completely dominant to the allele for single comb (p) . The alleles for black feature colour (B), and white feature colour (B') show codominance, so that BB' individuals possess blue features. If thickness heterozygous for both pairs of genes are matedm what proportion of offspring are expected to be pea combed and white feathered ?
