Multiple alleles can also encompass incomplete dominance and codominance along with simple or complete dominance for any given characteristic.
However, he only was able to describe simple or complete dominance patterns in individuals based on what he observed with those plants.
The inheritance of a trait phenotype that is determined by a gene located on one of the sex chromosomes is called sex linked inheritance.
Often these two topics are taught as separate chapters or sections within the larger curriculum unit that encompasses genetics.
Polygenic inheritance happens when traits are controlled by more than 1 gene. Now you are prepared to inspect the inheritance of two alleles that reside on distinct chromosomes.
In humans, there are hundreds of genes located on the X chromosome that have no counterpart on the Y chromosome.
The key difference between sex-linked and autosomal is that sex-linked inheritance occurs via the genes located on sex chromosomes X and Y chromosomes while autosomal inheritance occurs via the genes located on autosomes.
