They undergo independent assortment during meiosis.
B
They are involved in the same chemical reaction pathway.
C
They are expressed simultaneously in the same cell type.
D

Verified step by step guidance1
Understand the concept of linked genes: Linked genes are genes that are located close to each other on the same chromosome. Because of their proximity, they tend to be inherited together during the process of meiosis.
Explore the process of meiosis: Meiosis is the type of cell division that reduces the chromosome number by half, creating four haploid cells. During meiosis, homologous chromosomes can exchange genetic material through a process called crossing over.
Consider the role of crossing over: Crossing over can separate linked genes if it occurs between them. However, the closer the genes are on the chromosome, the less likely they are to be separated by crossing over, leading to their inheritance together.
Differentiate linked genes from independent assortment: Independent assortment refers to the random distribution of homologous chromosomes during meiosis, which applies to genes located on different chromosomes. Linked genes do not undergo independent assortment because they are on the same chromosome.
Conclude why linked genes are inherited together: The primary reason linked genes are inherited together is their physical proximity on the same chromosome, which reduces the likelihood of separation during crossing over in meiosis.
