Solution
The correct option is B Cytoplasmic inheritance
Cytoplasmic inheritance also known as extranuclear inheritance is the transmission of genes other than nuclear genes.
In vertebrates and higher plants, the egg is bigger and contains more cytoplasm than the sperm/male germ cell. Thus the inheritance of chloroplast and mitochondria, both of which are present in the cytoplasm is maternal.
Since chloroplast and mitochondria both contain their own genetic material, inheritance of their genomes is also known as cytoplasmic inheritance.
Quantitative inheritance is also known as a polygenic inheritance in which transmission of phenotypic traits whose expression depends on the additive effect of a number of genes.
