Incomplete Dominance is a type of inheritance in which one allele for a specific trait is not completely dominant over the other allele. This results in a combined phenotype (expressed physical trait).
For example, if you cross pollinate red and white snapdragon plants, the dominant allele that produces the red color is not completely dominant over the recessive allele that produces the white color. The resulting offspring are pink.

Actually the definition you provided is for co-dominance. In incomplete dominance the trait of the dominant allele is diminished because of a mutation and therefore if paired with a recessive trait the dominant trait will be muted. This still results in a pink color because muted red is pink, but the mechanism is different.
boo ya totaly awsome
adrianne you are wrong. what is written above is correct.
bio sux
t.heck is so right
agreed, the above is correct, just finished me homework- gratzi! ^_^
Bio doesnt suck, and the definition above is correct.
incomplete dominance- situation in which one allele is not completely dominant over another.
Codominance- situation in which both alleles of a gene contribute to the phenotype of the organism.
woooooooooooooooooooooooooow didnt understand a word u just said so it must be right weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee…………………………………………………………………………………………………
boo
Adrienne is right.
what you have provided is the definition for co-dominance, the correct definition for incomplete dominance is when the dominant allele does not completely maskthe effects of the recessive allele in the heterozygote.

Im doing bio-med at uni, definition is correct
Wow thanks for the answers biology rules!!!!!!!!!!!!!
Thanks Court your answer has cleared up my biology homework =)
thank you but i don’t know how to do punnett square its really hard and what is genotype, hetrozygous, homozygous. i will be happy if you explain this to me thank you
i didnt understand you all. . . .
you guys are all nerds and having nothing else to do except disagree with a correct defention. Ya man!!!
Wow all of you are nerds and have nothing to do but fight about a correct definition-Olivia. Ya man!!! Do work son!- Kyle
you can’t say anything kyle you were on here to!
If a brown patched tabbyfemale Manx is bred to a Lynxpoint male What colors would the kittens be and how many would be born manx?
If you breed a manx to a cat with a tail, is it possible for any Manx to be born?
Adrianne what you say does not make any sense. If the gene is mute it would not talk at all !! Incomplete dominance is like when you mix the same quantity of two colors and as neither color is stronger that the other what you get is a different color pink.
Moreover, you need to make research because she is not a junior or high school student. Let me remember you Adrianne that you are arguing with somebody that had several years study biology and writing book about science.
So the difference between Co-Dominance and incomplete dominance is that Co- dom is the expression of both allels. Incomplete is the expression of one intermediate trait.
Actually, Adrianne is correct. Although the original definition gets the right idea across, it does technically define co-dominance. Adrianne is a sharp student.
The “combined” phenotype is, indeed, codominance. Blood types are an example. If you have two alleles for type A, you have type A. If you have two alleles for type B, you have type B. But if you have one of each, you have type AB. If you have type O, you didn’t get either.
Incomplete dominance is when expression of the dominant trait is influenced (“muted” is a good word) by the presence of another allele — in this case, white.
How do I know this? I’ve been teaching biology for 22 years.
wait, i though codominance was when both genes are expressed fully…like blood type. and incomplete dominance was when neither gene is expressed fully…
j123 is correct and SWEnRQ provided an excellent example. However, a better way to look at it is to use flowers as an example. Take a pure breeding red flower and a pure breeding white flower and cross them. The results will be as follows:
A) If the red is dominant to the white, the resulting F1s are all red.
B) If the red is co-dominant with the white, the resulting F1s are all red and white spotted.
C) If the red and white display incomplete dominance, the resulting F1s are a shade of the combination of the two. (aka pink)
Hope this helped!
my,my,my… what a lot of controversy… I have to admit, BRT21, what you say makes sense
The above definition is correct. It is partially expressed.
what is above is ttttttttttttttttrrrrrrrrrrrrrrrrrrrrrrrruuuuuuuuuuuuuueeeeeeeeeeee!!!!!!!! I have my textbook right in front of my face and it says what Regina Bailey says!!!!!!!!!! Listen to her!!!!!!!!!!!!!!
thank you SWEnSRQ it makes a lot of sense.
tanxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
incomlete dominance – traits mixed
codominance -both traits show
great definition!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 it really helped me understand it. you are a very smart person. WHY ARE YOU SO SMART? I wish i was as smart as you…..
i bet im smarter than all of you.. lol jk
I came here 2 know the answer 4 my assignment….I thought this is really the answer….but now with all those comments……im stucked….which is really correct the definition above or adrianne’s answer???/
yeah!!!!
what ever…..
Now I’m confused I don’t know whether the definition above is really true or not… lemme tell you something Adrianne is the one who caused all the people to argue about the meaning of Incomplete Dominance….
Adrianne you are wrong, if it were co-dominance, the colour of the flower would be red AND white not a mixture of the two, (pink)
Your both right, red hair is a mutated gene and yes it does appear quite often. Master stop being annoying, it is in a way muted and yes both genes are emitting qualities. Both Andrianna and master are right just worded differently.
what is written above is right ; however co-dominance and incomplete dominance is closely relative to the point, but what differs is that incomplete dominance is INCOMPLETE( from the word itself) while in co-dominance both alleles contribute in the changes of the phenotypes
wow yall are smart
great definition brother!!
Incomplete dominance is when the alleles blend, resulting in a mix of the two phenotypes. An example is snapdragon flowers. Pink snapdragon flowers are produced from a white-red cross.
Codominance happens when an organism shows both of the parent’s phenotypes at the same time. A black cat and a tan cat reproducing creates a tabby cat. The tabby cat displays the phenotype of the black cat (stripes) and the tan cat at the same time.
ummmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm wow.
HEY!!!! We have the same name LOL
@Adrianne has a point. i think the definition bailey stated is co-dominance.
@Adrianne is right. i think the definition bailey stated is co-dominance.
WOW if you have computer access why dont you just go onto wikipidea or something and look up the answer.
Does Incomplete Dominance Nulifies Or Justifies Mendel’s Law?
Some of these answers are correct, some are partially correct, This link clears up the issue and very simply explains the difference between incomplete dominance and co-dominance. There is also a good example of a Punnit Square and how one works,

I think I speak for all of us when I say “Hey Arnold”
True.
Incomplete dominance will produce a third phenotype which contains the “blending” of the parental traits (Yellow + Blue = GREEN)
Codominance on the other hand, will also produce a unique phenotype in which both the parental traits will “appear together” (Red + White = Spotted red and white)
biology is fun
Adrianne is right
adraine you r wrong. the definition provided by bailey is correct. stay blessed.
well i tjink that is a dominant thing lmao idk what were tllking abt lol peace out 😝
The definition above is correct. Codominance is when BOTH alleles are expressed in the hybrid.
Cool and Hi
: P :q
thank u so much 4 the message….
lol@ you little kids
