Question

Strength of linkage is indirectly proportional to

• A. Distance between genes
• B. Number of chromosomes in the organism
• C. Synapsis
• D. Chiasma formation

Answer 1

The correct option is A

Distance between genes

Linked genes sit close together on a chromosome, making them likely to be inherited together. Genes on separate chromosomes are never linked. But not all genes on a chromosome are linked. Genes that are farther away from each other are more likely to be separated during a process called homologous recombination. So, strength of linkage depends on the distance between genes.
