Which of the following pairs is wrongly matched ?
XO type sex determination : Grasshopper
ABO blood grouping : Co - dominance
Starch synthesis in pea : Multiple alleles
T.H. Morgan : Linkage
As we learnt in
Alleles -
Genes which code for a pair of contrasting traits are known as alleles.
- wherein
They are slightly different forms of the same gene.
Starch synthesis in pea is controlled by pleiotropic gene. Pleiotropic gene has a multiple phenotypic effect because it can control expression of a number of characters.

This is incorrect.
Option 3)
Starch synthesis in pea : Multiple alleles
