Question
Linked genes are usually ________.
- found on the Y chromosome
- found on the X chromosome
- codominant
- located close together on a chromosome
Solution
Linked genes are usually located close together on a chromosome.
Explanation:
Linked genes refer to genes that are situated on the same chromosome and tend to be inherited together due to their proximity. The closer the genes are to each other on a chromosome, the less likely it is that a crossover event will occur between them during meiosis, which is when homologous chromosomes exchange segments of genetic material. Consequently, these genes can exhibit patterns of inheritance that are not consistent with Mendelian laws, specifically the law of independent assortment. They can assort together as a single unit, making it more likely that offspring will inherit particular combinations of traits. This phenomenon is critical in fields such as genetics and breeding programs, as understanding linkage can inform predictions regarding genotype and phenotype outcomes in offspring.
