CODOMINANCE & INCOMPLETE DOMINANCE & MULTIPLE ALLELES
How do you write an incompletely dominant phenotypic ratio?
4 red: 0 pink: 0 white
ow do you write an incompletely dominant genotypic ratio?
4NN:0Nn:0nn
How are codominant alleles notated?
A "C" for codominance and then superscript in uppercase of lowercase lettering depending on if the gene is dominant or recessive
How are codomianant heterozygotes different than simple heterozygotes?
A codominant heterozygote is a combination of forms of the allele, meaning both forms are present on that offspring.
What are multiple alleles?
A gene is controlled by more than two alleles, but an individual only has two of them, such as human blood type
How are incompletely dominant heterozygotes different than simple heterozygotes?
An incomplete dominant heterozygote is a completely different phenotype, as opposed to a normal heterozygote which shows the dominant phenotype
What is codominance?
Both forms of the gene are dominant, neither is recessive
How do you write a codominant phenotypic ratio?
Dominant, Mixed, Recessive
How do you write a codominant genotypic ratio?
Homozygous Dominant, Heterozygous CoDominant, Homozygous Recessive
What is incomplete dominance?
Incomplete dominance is when one trait doesn't completely dominate over the other allele, creating a new phenotype.
How are multiple allele relationships different than simple dominant/recessive?
More than one version of the gene/allele exist
How are incomplete dominance alleles notated?
Same as you would for a simple, beginner's punnet square
