Question 1 Report

Genes that remain linked are those

Answer Details
Genes that remain linked are those that are close to each other on the chromosomes. Chromosomes are structures in the cell that carry genetic information in the form of genes. Genes are segments of DNA that contain the instructions for making proteins, which are the building blocks of the body. In sexually reproducing organisms, such as humans, each parent contributes one chromosome to each pair of chromosomes in the offspring. As a result, offspring have two copies of each gene, one from each parent. Genes that are located close to each other on the same chromosome are more likely to be inherited together because they are physically close and cannot easily separate during the process of meiosis, which is the process by which cells divide to form gametes, such as sperm and eggs. Therefore, genes that remain linked are those that are close to each other on the chromosomes.
