The following points highlight the top three techniques used to study the genetics of human traits. The techniques are: 1. Pedigree Analysis 2. Amniocentesis 3. Twins. Technique # 1. Pedigree Analysis: Since, in human beings controlled crosses cannot be made, so human geneticists have to resort to a scrutiny of established matings in the hope that informative matings have been [...]
In this article we will discuss about:- 1. Methods of Inbreeding 2. Genetic Effects of Inbreeding 3. Inbreeding Depression 4. Practical Applications. The process of mating of individuals which are more closely related than the average of the population to which they belong, is called inbreeding. For example, parthenogenesis in animals and apomixes and self-fertilization in plants are the most [...]
Regarding the genetic structure of the population, the following two hypotheses have been proposed:- 1. Classical Hypothesis 2. Balance Hypothesis. Model # 1. Classical Hypothesis: It was developed by T.H. Morgan (1932) and supported by H.J. Muller and Kaplan (1966). The classical hypothesis proposes that the gene pool of a population consists at each gene locus of a wild-type allele [...]
