A key difference between phenotype and genotype is that, whilst genotype is inherited from … WebThis phenomenon is called genetic linkage. When genes are linked, genetic crosses involving those genes will lead to ratios of gametes (egg and sperm) and offspring types that are not what we'd predict from Mendel's law of independent assortment. Let's take a closer look at why this is the case. What is genetic linkage?
