Verified
If two genes are on the same chromosome, ____.
A) crossing over occurs frequently
B) they assort independently
C) they are in the same linkage group
D) they are segregated during meiosis
E) an inversion will usually occur
Linkage Group
All of the genes on a chromosome.
Same Chromosome
Pertains to genes or genetic markers located on the same chromosome, which may exhibit linkage during inheritance.
Crossing Over
The process of exchange of genetic material between homologous chromosomes during meiosis, leading to new combinations of genes.
- Describe the impact of linkage and crossing over on gene assortment.

Final Answer :
C
Explanation :
Genes on the same chromosome are said to be in the same linkage group. This means that they tend to be inherited together and are less likely to undergo independent assortment. Crossing over does occur between genes on the same chromosome, but it is less frequent than between genes on different chromosomes. Segregation during meiosis also occurs, but it is not affected by whether the genes are on the same chromosome or not. An inversion may or may not occur, depending on whether there has been a chromosomal rearrangement.
