Which of the following statements is true regarding linked genes in organic chemistry reactions?
A
Linked genes can be separated by independent assortment during meiosis.
B
Linked genes are always inherited together because they are located on the same chromosome.
C
Linked genes are always expressed together in the phenotype.
D
Linked genes are located on different chromosomes and assort independently.
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 meiosis, the process of cell division that results in gametes.
Consider the process of meiosis: During meiosis, homologous chromosomes are separated into different gametes. However, genes that are close together on the same chromosome (linked genes) do not assort independently because they are physically connected.
Evaluate the statement about independent assortment: Independent assortment refers to the random distribution of different genes located on different chromosomes into gametes. Linked genes do not follow this pattern because they are on the same chromosome.
Analyze the statement about inheritance: Linked genes are often inherited together because they are located on the same chromosome. This means that they do not assort independently like genes on different chromosomes.
Consider the expression of linked genes: While linked genes are inherited together, they are not necessarily always expressed together in the phenotype. Expression depends on other factors such as dominance, epistasis, and environmental influences.
