Question : All genes located on the same chromosome

Answer»

Form DIFFERENT groups depending upon their relative distance
Form one linkage group
Will not form any linkage groups
Form interactive groups that affect the phenotype.

Solution :A group can be defined as a group of linked gene (on the same CHROMOSOME) and corresponds to the genome of ORGANISM, like HUMAN has 23 linkage groups, pea and Neurospora has 7 linkage groups, Drosophila has 4 linkage groups. Linkage group in a species corresponds to its haploid number of chromosomes.
