Question

A) differentiate between dominance and co-dominance. (b) explain co-dominance taking an example of human blood groups in the population

Answer 1

When one allele for a specific trait does not completely dominate over the other allele, and therefore the phenotype produced is the complete mixture of both dominant and recessive allele is known as Incomplete Dominance. While in Co-Dominance both the allele for a specific trait are equally expressed. The resultant phenotype will express both the character equally of both participating alleles.

As stated by Gregor Mendel, traits are inherited by the transfer of genes from parents to their offspring. Genes are the segments of DNA located on the chromosomes, which are passed from one generation to the other. There are typically two alleles, for each trait or characteristics inherent by the animal cells. These paired alleles can be heterozygous (having different alleles) or can be homozygous (having identical alleles) for a given trait.

Usually, heterozygous dominance is noticed in animal cells like in the case of complete dominance, co-dominance, and incomplete dominance. Although there is the lot of confusion between incomplete dominance and co-dominance. The main difference lies in the pattern of gene expression.

In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
