Question

A. The physical association between the two genes is termed as $(a)$ ____ .
B. The generation of non-parental gene combination is termed as $(b)$____ .

• A. a - recombination, b - crossing over
• B. a - recombination, b - linkage
• C. a - linkage, b - recombination
• D. a - linkage, b - mutation

Answer 1

Answer: (C)

Linkage: It is the tendency of genes to remain together even during the formation of gametes. This is due to the physical association or linkage between the $2$ genes. In such cases, parental gene combinations remain higher than the non-parental gene combinations (recombinants).
Recombination: It is the tendency of the generation of non-parental gene combinations. In such cases, non-parental gene combinations (recombinants) remain higher than the parental gene combinations.
