Describe the differences among dominance, incomplete dominance, codominance, and overdominance.

Expert Solution & Answer

Summary Introduction

To review:

The differences between dominance, over dominance, co-dominance, and incomplete dominance.

Introduction:

Genetic inheritance takes place due to the genetic material in the form of DNA or deoxyribonucleic acid which is passed on from the parents to their infants or offspring. Inheritance pattern can be dominant, recessive, co-dominant, orincomplete dominant.

Explanation of Solution

The differences between dominance, co-dominance, overdominance, and incomplete dominance is given in the table below:

Dominance	Overdominance	Codominance	Incomplete dominance
Only dominant allele expresses its phenotype while the recessive ones remain suppressed.	It is the condition in which heterozygous expression of phenotype is superior because of its beneficial effect.	Both the alleles will express their phenotype simultaneously.	It occurs when two alleles produce an intermediate phenotype.
Only one phenotype is expressed because of expression of only the dominant allele.	Expression of alleles in heterozygous condition.	Equal expression of both the allelessimultaneously.	Both the alleles are expressed partially at a time.
Phenotype is similar to one of the parental alleles.	No new phenotype is formed.	It generates a different phenotype from the parental ones.	An intermediate phenotype is generated.
Example: Mendelian traits in pea’s plant(Pisum sativum).	Example: Sickle cell anemia in humans.	Example: ABO blood group characters in human.	Examples: Production of pink coloured flower in Mirabilis jalapa.

Conclusion

Therefore, it can be concluded that dominance means expression of phenotype of only one allele over another allele. Overdominance refers to the expression of phenotype of the heterozygotes which is superior to homozygotes. Incomplete dominance refers to the condition when both the heterozygotes show an intermediate phenotype. In co-dominance, both the alleles in the heterozygote will express their effects independently.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?

Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?

Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
