Solution
The correct option is D Polygenic inheritance
Polygenic inheritance refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes. In monogenic inheritance, the trait results from the expression of one gene (or one allele pair). Example: Inheritance of skin colour in human being.
In point mutation, there is a change in only one base pair of DNA due to substitution.
A chromosomal aberration is a missing, extra, or irregular portion of chromosomal DNA.
Codominance is the condition where neither allele can mask the expression of the other, that is, neither allele is completely dominant, hence they are both expressed together.
So, the correct answer is "option D".
