Question

Describe complete linkage and incomplete linkage

Answer 1

.$\bf\large\underline\green{Answer:-}$

I. Complete linkage :

The linked genes which are closely located on the chromosome do not separate (no crossing over) and inherit together. They are called completely linked (strongly linked) genes and the phenomenon of their inheritance is called complete linkage. Thus the parental traits are inherited in offsprings. e.g. X chromosome of Drosophila males- show complete linkage.

II. Incomplete linkage :

The linked genes which are distantly located on the same chromosome and have chances of separation by crossing over, are known as incompletly linked (weakly linked) genes. The phenomenon of their inheritance, is called incomplete linkage. Thus, new traits occur in offsprings. e.g. In Zea mays - colour and shape of grain show incomplete linkage.

Answer 2

Answer:

complete linkage is exhibited when the genes for a particular character are present very close to one another... On the other hand, incomplete linkage occurs when the Genes for different characters are separated at the time of gamete formation due to breaking and exchange of chromosome pieces during meiosis .
