When a cluster of genes show linkage behaviour they (1)Do not show a chromosome map (2)Show recombination during meiosis (3) Do not show independent assortment (4)Induce cell division
Answers
Answer:
Linkage is referred to the phenomenon wherein alleles located close together on a chromosome show tendency to be inherited together during meiosis. Genes present near to each other have less probability of being separated onto different chromatids during chromosomal crossover. Therefore, when a cluster of genes show linkage behaviour they do not show independent assortment. Genes showing linkage behaviour do not assort independently and hence, do not show recombination during meiosis. Linkage map shows relative position of genes on the chromosomes based on recombination frequency between them; the map show both linked and independently assorted genes.
Thus, the correct answer is option C.

(1)Do not show a chromosome map
(2)Show recombination during meiosis
(3) Do not show independent assortment✔✔
(4)Induce cell division
