If an offspring shows a phenotype that is intermediate between the phenotypes of the parents what is this type of inheritance?

Incomplete dominance can create offspring that display a trait not identical to either parent but intermediate to the two. One example of incomplete dominance is a red flower and a white flower crossbreed to form a pink flower.

Pattern of inheritance in which both alleles contribute to the phenotype of the organism?
The pattern of inheritance in which both alleles contribute to the phenotype of the organism is codominance. For example white and red hair color in cattle. Black and white feather color in certain chickens.
Define and distinguish between pleiotropy and polygenic inheritance?
Pleiotropy: one gene affects many traits (phenotypes) Polygenic: many genes affect one trait (phenotype)
Which of the following statements about a gene that shows maternal effect inheritance is true?
Offspring will show a mutant phenotype if the mother has a mutant genotype.
When inheritance of a particular trait follows a pattern of what individuals that are heterozygous for the trait have the same phenotype or physical characteristic as individuals who are homozyg?
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
What is a imcomplete dominance?
Incomplete dominance is a form of intermediate inheritance where one allele for a trait is not dominant over anther allele. Because of this, a combined or "mixed" phenotype results. For example, if a red flower is crossed with a white flower, and the offspring is pink, this is considered incomplete dominance.
When types of selection occurs when individuals in a population with the intermediate phenotype are selected for?
Stabilizing selection occurs when organisms with intermediate phenotypes are selected for.
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.

The pattern of inheritance in which both alleles contribute to the phenotype of the organism is codominance. For example white and red hair color in cattle. Black and white feather color in certain chickens.
Why is there a wide range of phenotypes in polygenic inheritance?
"polygenic inheritance"- the inheritance of quantitative traits, traits which are influenced by multiple genes. Polygenic inheritance shows how multiple genes in combination with a person's environment can influence someone's phenotype, or physical appearance. A wide range is produced because the gene combinations are vast.
What is the phenotype of all four offspring's?
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
Explain the difference between intermediate inheritance and codominance?
In codominance, neither phenotype is recessive. Instead, the heterozygous individual expresses bothphenotypes. Intermediate inheritance is when neither allele is dominant to another, but a mixture is produced in the 2 alleles present. A mixed phenotype is given that is between the two parents phenotype .e.g Red flowers (RR) crossed with white flowers (WW) produces pink flowers (RW).
What are The observable traits of an organism are?
phenotype
Does incomplete dominance lead to intermediate phenotypes?
Yes. A sort of blending of the genes are shown as the phenotype. An example of this is the mixing of white rose and a red rose which will result in a pink rose.
