Differences in qualitative and quantitative genetics

Qualitative genetics	Quantitative genetics
1. It deals with the inheritance of traits of kind, viz., form, structrue, colour, etc.,	1. It deals with the inheritance of traits of degree, viz., height or length, weight, number, etc.,
2. Discrete phenotypic classes occur which display discontinuous variations.	2. A spectrum of phenotypic classes occur which contain continuous variations.
3. Each qualitative trait is governed by two or many alleles of a single gene.	3. Each quantitative trait is governed by many non-allelic genes or polygenes.
4. The phenotypic expression of a gene is not influenced by environment.	4. Environmental conditions effect the phenotypic expression of polygenes variously.
5. It concerns with individual matings and their progeny.	5. It concerns with a population of organisms consisting of all possible kinds of matings.
6. In it analysis is made by counts and ratios.	6. In it analysis is made by statistical methods.

Qualitative genetics:

It is the study which deals with inheritance of qualitative traits such as structure, colour, etc.,

Quantitative genetics:

It is the study which deals with the phenotypes which vary continuously as opposed to discretely identifiable phenotypes and gene products.

1.) Compare and contrast population genetics with Mendelian genetics of individuals and molecular genetics. 2.) What are the two Hardy-Weinberg conclusions and why are they both needed? 3.) What use is the Hardy-Weinberg equilibrium principle? 4.) What are the 5 crucial assumptions of the Hardy-Weinberg equilibrium principle? 5.) Describe the ADH study and explain its relevance. 6.) Why won’t CCR5- Δ32 allele increase in frequency?
