If an offspring shows a phenotype that is intermediate between the phenotypes of the parents what is this type of inheritance?
This type of inheritance is known as incomplete dominance. In incomplete dominance, the heterozygote phenotype is a blend or mix of the phenotypes displayed by the two different homozygote parents.

When a cross between a red flower and a white flower yeilds pink offspring the trait is?
Incomplete dominance, where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.
What is the type of inheritance that would suggest the concept of blending?
Blending inheritance suggests a type of inheritance where the traits of the parents are mixed together in the offspring, resulting in an intermediate phenotype. This concept contrasts with the idea of particulate or Mendelian inheritance, where discrete units (alleles) are passed from parents to offspring without blending.
What is the phenotype of each parent and of the offspring?
The phenotype is the physical or observable characteristics of an organism. The phenotype of each parent contributes to the phenotype of the offspring through genetic inheritance. The offspring will exhibit a combination of traits from both parents, resulting in a unique phenotype.
Pattern of inheritance in which both alleles contribute to the phenotype of the organism?
Codominance is the pattern of inheritance in which both alleles contribute to the phenotype of the organism. This means that neither allele is dominant or recessive, and both are expressed in the phenotype of the individual.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
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.
How do you describe a pattern of inheritance that the blending hypothesis fails to explain?
A pattern of inheritance that the blending hypothesis fails to explain is incomplete dominance, where the heterozygous phenotype is intermediate between the two homozygous phenotypes. This contradicts the blending hypothesis, which suggests that the traits of the parents are mixed together in the offspring. In incomplete dominance, the traits remain distinct in the offspring.
When a cross between a red flower and a white flower yeilds pink offspring the trait is?
Incomplete dominance, where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.

Blending inheritance suggests a type of inheritance where the traits of the parents are mixed together in the offspring, resulting in an intermediate phenotype. This concept contrasts with the idea of particulate or Mendelian inheritance, where discrete units (alleles) are passed from parents to offspring without blending.
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.
What is the phenotype of each parent and of the offspring?
The phenotype is the physical or observable characteristics of an organism. The phenotype of each parent contributes to the phenotype of the offspring through genetic inheritance. The offspring will exhibit a combination of traits from both parents, resulting in a unique phenotype.
What type of selection may eliminate intermediate phenotypes?
Disruptive selection can eliminate intermediate phenotypes by favoring extreme phenotypes, leading to a bimodal distribution. This selection occurs when individuals with extreme traits have a higher fitness than those with intermediate traits, resulting in the reduction of the intermediate phenotype in the population.
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.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
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.
Pattern of inheritance in which both alleles contribute to the phenotype of the organism?
Codominance is the pattern of inheritance in which both alleles contribute to the phenotype of the organism. This means that neither allele is dominant or recessive, and both are expressed in the phenotype of the individual.
Explain the difference between intermediate inheritance and codominance?
Intermediate inheritance refers to a situation in genetics where the heterozygous phenotype is a blend of the two homozygous phenotypes, such as in the case of flower color in snapdragons. Codominance, on the other hand, is a situation where both alleles of a gene are expressed fully in the heterozygous individual, resulting in a phenotype that shows traits of both alleles simultaneously, like in the case of human blood types.
True or false the phenotype of the herozygote is intermediate of for incomplete dominance?
True. In incomplete dominance, the heterozygote exhibits an intermediate phenotype that is a blend of the two homozygous phenotypes. This is different from complete dominance, where the dominant allele completely masks the expression of the recessive allele in the heterozygote.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
