👉 Non-homologous refers to a situation where two or more genes are expressed in different cells of the same organism, leading to variations in phenotype. This can occur due to genetic mutations that alter the expression levels of these genes, resulting in differences in their function and response to environmental factors. Examples of non-homologous gene pairs include: 1. Homologous genes: These are genes that have identical sequences within them but are located on different chromosomes or are part of the same chromosome.
