Question
All genes located on the same chromosome
Options
A.Form different groups depending upon their relative distance
B.Form one linkage group
C.Will not from any linkage group
D.Form interactive group that affect the phenotype
Solution
Sol.(b) [Key Concept: Linkage Groups — All Genes on Same Chromosome] All genes located on the SAME chromosome form ONE LINKAGE GROUP. The number of linkage groups in a species equals the number of different chromosomes (haploid number). In humans (n=23), there are 23 linkage groups. All genes on chromosome 1 form linkage group 1, all on chromosome 2 form linkage group 2, etc. Genes within a linkage group tend to be inherited together (unless separated by crossing over).
