Is incomplete dominance caused by each allele equally influences the offspring?

not really. that would be co-dominance. incomplete dominance is when a heterozygote genotype is expressed as intermediate between the two alleles. for example: if you cross a red snapdragon (RR) with a white snapdragon (WW) all the offspring will be RW which will code for a different color, such as pink.

Incomplete dominance and co-dominance?
They both are equal in dominance (neither are recessive). For example, incomplete dominance is when two genes are equally expressed at once, such as if you bred a red snapdragon and a white snapdragon you would end up with a pink snapdragon because both the red and white genes are dominant. In codominance instead of the genes blending together (Red and white blending into pink) they are equally dominant but retain their original characteristics. For example if a white cow and red bull mated and had a roan cow instead of being one color it would have brown and red spots. Incomplete dominance and codominance are alike in those ways by having two different both equally dominant genes present at one moment
If both alleles are equally expressed in a heterozygote the relationship is called?
The expression of more than one allele is referred to as incomplete dominance. For example a flower that is heterozygous red and white will have a pink phenotype.
What is expressed when both alleles for a gene are equally expressed as in human blood type?
This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type
Mendels conclusions and exceptions on genetics?
1.Partial dominance - red x white gives pink. 2.Incomplete dominance - red cattle x white cattle give a mix of both = roan. 3.Multiple alleles - eg ABO blood groups. 4.Epistasis - due to interaction of two or more genes. 5. One gene, many traits 6. Many genes, one trait
What would happen if homologous chromosomes did not pair in prophase 1?
if homologous chromosomes didn't pair up in Prophase 1 the DNA between the parents isn't distributed equally to the offspring, or variation would not occur.
What is the condition in which two different alleles are expressed equally when inherited?
Codominance.Codominance
What occurs when different traits are equally dominate and each allele has its own degree of influence?
incomplete dominance
When one black mice are introduced to white mice and grey mice are created what is this called?
Since grey is an intermediate color created from the parental colors black and white, this is an example of incomplete dominance. In incomplete dominance, the offspring receives an allele for color from each parent in wiich there is no complete dominance (no letter oding (allele) in itsel is not domiant or more powerful than the other), therefore the alleles are equally powerful and the colors blend to form an intermediate. fAnother example of incomplete dominance would be pink flowers resulting from parents colored red and white

Is it true that multiple alleles can be studied only individuals?
Multiple alleles refers to there being more than two alleles for a particular trait. Incomplete dominance is when one allele does not completely mask another (as is usually the case in simple Mendelian inheritance) but instead the two traits are expressed equally. For example, if a red cow (RR) mates with a white cow (WW), their offspring will not be white and red, but a mixture of the two colors roan (RW). That is incomplete dominance.
What is the difference between incomplete dominance and codominance?
co dominance is when there is no dominant or reccessive traits just lie in in incomplete dominance the diffrence is in co dominance the are mkore chromosomes
What type of dominance is demonstrated if a yellow bird and a red bird have an orange baby bird?
Incomplete dominance. Since neither gene is dominant over the other, both traits are shown, thus giving a combination of colors. The same thing happens when a red flower and white flower crossbreed and produce pink offspring--the genotype for color is equally dominant and combines an allele from both parents.
If both alleles are equally expressed in a heterozygote the relationship is called?
The expression of more than one allele is referred to as incomplete dominance. For example a flower that is heterozygous red and white will have a pink phenotype.
How does codominance change the offsprings phenotype?
Codominance is contrary to typical mendelian genetics, in that no one allele is dominant to the other, so they are both expressed equally. The important part is that the offspring with express each allele independently, such as having spots of one color, then spots of another color, instead of blending the two colors, which would be incomplete dominance. So codominance changes the offsprings phenotype by making the offspring express both alleles equally, yet each allele's expression is separate/distinguishable, not blended.
What is it called when neither allele for a trait is dominant?
There are two cases where this can happen: Case 1: Codominance: Both alleles are equally present but are distinct. a good example of this is when you breed a white cow with a red cow. both white and red are dominant. when you look at the offspring, it is roan; it has both white and red hairs mixed in with each other. Case 2: incomplete dominance: Both alleles are equally present but are not distinct. a good example of this is is when you mix a white flower and a red flower and you get a pink flower
What is expressed when both alleles for a gene are equally exprssed as in human blood type?
co dominance
What does co-dominance mean in genetics?
Codominance is when neither trait is dominant nor recessive. Both traits are equally likely to occur and the offspring is often from a blending trait. For example, if two co dominant animals mate and one is brown and the other is white, the offspring will be a blending of both colors.
