Complex Patterns of Inheritance
By Edgar G.
Multiple Alleles
An allele of a genetic locus having more than two allelic forms within a population.
There are multiple phenotypes.
Human ABO Blood type, rabbit coat color
Incomplete Dominance
One allele does not completely dominate another allele, and therefore results in a new phenotype.
Different
wavy hair from parent with straight and parent with curly, grey sheep
Codominance
A relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent.
merge, different
short hair and long hair dogs produce medium hair offspring, high voice low voice produces medium voice
Polygenic Traits
One whose phenotype is influenced by more than one gene.
influenced more by one trait
Height, voice, hair etc.
