Which of the following pairs is wrongly matched ?
Which of the following pairs is wrongly matched ?
The correct option is B Starch synthesis in pea : Multiple alleles
XO type sex determination pattern is found in certain insects. In this method of sex determination, a female has two X chromosomes (called XX) while the male has only one X chromosome (called XO). For example, Grasshopper.
Starch synthesis in pea is controlled by a single gene having alleles B and b.
Linkage is a phenomenon of genetic inheritance in which genes of a particular chromosome show their tendency to inherit together. Linkage was discovered by T.H. Morgan in Drosophila melanogaster.
Codominance is a phenomenon in which both alleles of a pair express themselves fully in the F1 hybrid. A good example of codominance is human ABO blood grouping in which the four main blood groups A, B, AB and O controlled by three alleles.
So, the correct answer is option 2
