Complete linkage and incomplete linkage definition
Answers
Explanation:
Incomplete Linkage of Gene:
Complete linkage between genes on the same chromosome is rare. ... Linkage is a physical relationship between genes and can be modified by a physical crossing over during meiosis between gene pairs on homologous chromosomes.
Complete linkage:- This type of is when genes always show parental combination.
Some Special Points:-
➤ It never forms new combination.
➤ Crossing overis absent in it.
➤ Such genes are found amd are very close on the chromosomes.
➤ Also these type of linkage is very rare in nature.
Incomplete linkage:- When new combinations(<50%) also appear along with parental combination in offsprings, this type of linkage is known as incomplete linkage.
Some Special Points:-
➤ The new combinations are formed due to crossing Over
➤ It's unit is centi Morgan.
➤ Distance between linked genes is identified by incomplete linkage.
