WebLinked genes : The two or more genes are said to be linked when they are located on the same chromosome and cannot segregate independently as they are inherited together. The linked genes are arranged linearly. Example of linked genes is Drosophila: The cross … WebHowever, when considering linked genes the location of each gene and allele often needs to be represented. For example, a dihybrid BbEe can have one chromosome with both dominant alleles (BE) or one chromosome with a dominant allele for one gene and recessive allele for the other (Be for example).

WebY-linked Inheritance. If the mutated gene is present in the Y chromosome, then this is referred to as Y-linked inheritance. Since the Y chromosome is present in males only, Y-linked disorders are passed from fathers to male offspring. Hypertrichosis (presence of long dark hair on the ears) is an example of Y-linked inheritance. WebFeb 7, 2024 · Genes located on the sex chromosomes are called sex-linked genes.
