You asked: Which occurs when a heterozygous phenotype is an intermediate phenotype between two homozygous phenotypes?

Incomplete dominance describes situations in which the heterozygote exhibits a phenotype that is intermediate between the homozygous phenotypes. Codominance describes the simultaneous expression of both of the alleles in the heterozygote.

When a heterozygous phenotype is intermediate between the two homozygous phenotypes is called?

This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.

When a heterozygous phenotype is intermediate between the two homozygous phenotypes eg pink flowers from red and white parents this is an example of?

Incomplete dominance is when traits are inherited in a pattern where the phenotype of heterozygous individuals is intermediate between those of two homozygotes.

When a heterozygous individual expresses a phenotype intermediate between the dominant and recessive phenotype this is called?

Terms in this set (23) Codominance. the relation between two alleles of a gene, such that both alleles are phenotypically expressed in heterozygous individuals. Incomplete Dominance. a pattern of inheritance in which the heterozygous phenotype is intermediate between the two homozygous phenotypes.

What do you call it when a heterozygous organism has a phenotype somewhere in between the two homozygous phenotypes red & blue purple?

In incomplete dominance the heterozygous phenotype lies somewhere between the two homozygous phenotypes. What is codominance. when both alleles contribute to the phenotype. This means the phenotypes produced by both alleles are clearly expressed.

Which type of dominance occurs when the heterozygote has the same phenotype as one of the homozygotes?

Incomplete dominance and codominance

The results of Mendel established that genes can exist in two alternate forms (i.e., one dominant and other recessive). The dominant allele expresses the same phenotypic effect in heterozygotes as in homozygotes (i.e., Aa or AA are phenotypically similar).

Which inheritance pattern is characterized by heterozygous organisms who exhibit an intermediate phenotype?

dominance is an inheritance pattern in which heterozygous organisms exhibit an intermediate phenotype.

What is the phenotype of a heterozygous snapdragon flower?

In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R) and white (R’). The heterozygous genotype is expressed as pink.

Which of the following is an example of incomplete dominance?

Chickens with blue feathers are an example of incomplete dominance. When a black and a white chicken reproduce and neither allele is completely dominant, the result is a blue-feathered bird.

What occurs when the heterozygous individual is phenotypically intermediate between the 2 homozygous individuals?

Section Summary. Alleles do not always behave in dominant and recessive patterns. Incomplete dominance describes situations in which the heterozygote exhibits a phenotype that is intermediate between the homozygous phenotypes. Codominance describes the simultaneous expression of both of the alleles in the heterozygote.

When both alleles are expressed in a heterozygous individual?

Codominance describes the simultaneous expression of both of the alleles in the heterozygote. Although diploid organisms can only have two alleles for any given gene, it is common for more than two alleles for a gene to exist in a population.

What does dominant vs recessive mean?

(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes).

What occurs when the phenotype of a heterozygous offspring is blended?

Codominance. Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote.

How would you describe the phenotype of a homozygous dominant a heterozygous A?

While individuals that are homozygous for a trait express one phenotype, heterozygous individuals may express different phenotypes. In genetic dominance cases in which complete dominance is expressed, the phenotype of the heterozygous dominant allele completely masks the recessive allele phenotype.

What occurs when the phenotype of the parent is both expressed the phenotype of the offspring?

Codominance. As opposed to partial dominance, codominance occurs when the phenotypes of both parents are simultaneously expressed in the same offspring organism.
