Yes. Heterozygous dominance offers a way to preserve the mutated allele.

Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!
How many alleles influence a phenotype in incomplete dominance?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
What is an example of a heterozygous chromosome?
It's the gene that would be heterozygous not the chromosome.
What is a non example of heterozygous?
Heterozygous
What is a Co-dominant alleles disorder?
One example is Huntington's Disease. With a recessive genetic disorder, to develop the disorder, you must inherit the gene from BOTH parents (odds, 1 in 4). With a dominant gene disorder, if you inherit the gene from ONE parent, you will develop that disorder (odds- 1 in 2).

What is a complete dominance?
Complete dominance is a genetics concept used in heterozygous alleles. The dominant allele completely suppresses expression of the recessive one so that a homozygous dominant and a heterozygous individual are phenotypically indistinguishable.
One allele is not completely dominant over another The heterozygous phenotype is somewhere in between the two homozygous phenotypes?
You get aspects of each trait displayed. Like, if one cat had a solid colored orange fur, and it's mate was brown, you could get a mottled cat. Or if one parent has brown eyes, and the other green, hazel eyes could occur.

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.
A example of a homosygous genetic disorder?
Cystic Fibrosis is a recessive homozygous genetic disease
What is an example of a heterozygous chromosome?
It's the gene that would be heterozygous not the chromosome.
What is a non example of heterozygous?
Heterozygous
What is hepatitus?
Hepatopathy is a disease or disorder of the liver. It is a very general term used when there is some sort of problem with the liver. The suffix 'pathy' can be added to many organs to describe a disease or disorder. For example gastropathy is a disease or disorder of the stomach.
What is an example of a genetic disorder resulting from a mutuation?
-Cystic Fibrosis -Hemophilia -Tay-Sachs disease
What is opathy?
relating to medical terms.... "-pathy" is a word suffix that denotes a disease or disorder. Example: Neuropathy is a nervous system disease.
How is a snap dragon an example of incomplete dominance?
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
