Deviation from Mendelism
Deviation from Mendelism: Overview
This topic consists of various concepts like Deviation from Mendelism,Pleiotropy,Polygenic Inheritance, etc.
Important Questions on Deviation from Mendelism
The fundamental cause of the sickle-cell disease is a change in the structure of:
When one gene controls two or more different characters simultaneously, the phenomenon is called
Which one of the following pairs of features is an excellent example of polygenic inheritance?
Grain colour in wheat is determined by three pairs of polygene. Following the cross AABBCC (dark colour) and aabbcc (light colour), in generation, what proportion of the progeny is likely to resemble either parent?
A single point mutation in gene 'X' results in breathing difficulty, hypertension as well as partial sterility. Which among the following phenomenon best explains the observed phenotype?
The phenomenon of pleiotropism refers to:
A quantitative character is controlled by four polygenes. Find out probability of parental plant in F₂ generation ?
In case of duplicate genes which are non-allelic then what will be possibility of being triangular seeds when gene A and gene B are present separately in plants?
How many types of phenotypes are formed in polygenic inheritance of wheat kernel colour?
Which one of the following genotypes can form only 2 different types of gametes?

Which law of Mendel is discarded by incomplete dominance?
One of the following is quantitative abnormality of polypeptide globin chain synthesis
Extranuclear inheritance (cytoplasmic inheritance) is $a$ consequence of presence of genes in
Human skin color is controlled by several gene pairs. Let us assume here that there are just three gene pairs on different chromosomes and that for each pair there are two alleles - an incompletely dominant one that codes fo melanin deposition. If a very dark-skinned person marries a very light-skinned woman, what will be the chance that their offspring will have very dark skin.
What is the skin colour in man an example of?
