How are phenotypes inherited

WebSex linkage referes to a gene being linked to (or "on") a sex chromosome. Gene linkage refers to two genes that are on the same chromosome, and are thus "linked" … Phenotypes are determined by an interaction of genes and the environment, but the mechanism for each gene and phenotype is different. For instance, an albino phenotype may be caused by a mutation in the gene encoding tyrosinase which is a key enzyme in melanin formation. However, exposure to UV radiation can increase melanin production, hence the environment plays a role in this phen…
