Match the following
| Column I | Column II |
| I. Codominance | A. Blue color in Andalusian fowls |
| II. Multiple alleles | B. AB blood group in humans |
| III. Recessive traits | C. Coat colour in rabbits |
| IV. Incomplete dominance | D. Wrinkled seed shape in pea |
The correct option is B I - B, II - C, III - D, IV - A
AB blood groups in humans are produced due to the co-dominant nature of alleles A and B. When an individual inherits one IA and IB from their parents, both alleles will express their traits resulting in the phenotype of AB blood group.
Coat colour in rabbits is controlled by four alleles that exist for the C gene. The wild-type version CC is expressed as brown (agouti) fur. The chinchilla phenotype, Cch Cch, is expressed as black-tipped white fur. The Himalayan phenotype, Ch Ch, has black fur on the extremities and white fur elsewhere. Finally, the albino, or “colourless” phenotype, c / c, is expressed as white fur.
Seed shape was one of the seven characteristics of the pea plant picked up by Mendel for his experiments. The wrinkled seed shape is a recessive trait, while the round shape is dominant.
Andalusian fowls have two pure forms, black and white which are controlled by incompletely dominant alleles. When fowls with black and white colour are crossed, the resulting offspring has blue colour. This is an example of incomplete dominance.
