Compare and contrast the terms codominance and incomplete dominance.
To write:
The comparison characters between incomplete dominance and co-dominance.
Introduction:
The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition.
Explanation of Solution
The incomplete dominance is a condition, in which an allele is not able to masks the effect of the recessive allele and the co dominance is a condition, in which 2 alleles are equally dominant resulting in expression of both traits.
The comparison between incomplete dominance and co dominance is given below:
Incomplete dominance | Co dominance. |
Incomplete dominance is a heterozygous condition in which neither allele in pair shows complete dominance over the other. Neither of the allele in the pair is dominant and rather combines to display an intermediate trait by mixing of the two traits. For Example:
This can be observed in the flower color of the snapdragon plants. The color of the flower is determined by two types of alleles: R and r. R is the dominant allele and codes for red flowers. The r is the recessive allele and codes for the white flowers. | Co dominance is a condition, in which two alleles are equally dominant. In this condition, the resultant phenotype is the cumulative expression of both the alleles.
For Example: This can be observed in the ABO blood grouping of the humans. There are three allele, which exist in humans and determine the blood group, these are Ia, I b and i. The allele Ia, I b are dominant and code for A and B phenotype respectively and the allele i code for blood group O and it is recessive. In the presence of Ia, Ib, the resulatant phenotype is AB. |
The incomplete dominance is a condition, in which an allele is not able to masks the effect of the recessive allele and the co dominance is a condition, in which 2 alleles are equally dominant resulting in expression of both traits.

Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?arrow_forwardA patient visits her doctor with symptoms typical of a bladder infection.
