Pleiotropy

  • Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect.

When both alleles can be observed in a phenotype the interaction is called?

When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles


How does codominance effect phenotype?

Codominance occurs when both alleles contribute to the phenotype of a heterozygous individual. This results in a phenotype that displays characteristics of both alleles simultaneously, rather than blending them. This can lead to unique patterns or color combinations in the phenotype.


When both alleles are expressed in an offspring this is called?

codominance. In codominance, both alleles contribute to the phenotype and are fully expressed in the offspring. This results in a distinct phenotype that is a combination of the traits associated with each allele.


What is an inheritable pattern in which two different alleles contribute to the phenotype in separate and distinguishable ways?

Codominance is an inheritable pattern where two different alleles for a gene are both expressed in the phenotype, resulting in a unique trait that displays characteristics of both alleles. This leads to a distinct phenotype that is a combination of the traits produced by both alleles.


In a heterozygous genotype the alleles always shows in the phenotype.?

In a heterozygous genotype, where an individual possesses two different alleles for a particular gene, the phenotype can be influenced by the dominance relationship between the alleles. Typically, the dominant allele will mask the expression of the recessive allele, resulting in the phenotype reflecting only the dominant trait. However, in some cases, such as incomplete dominance or codominance, both alleles can contribute to the phenotype. Therefore, it is not accurate to say that both alleles always show in the phenotype.

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.

What do geneticists call alleles that are both expressed in the phenotype when they are together?

Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.


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 the interaction of two alleles in which both alleles can be observed in a phenotype?

Codominance is the interaction of two alleles where both alleles are equally expressed in the phenotype, resulting in a mixed or blended phenotype. This means that the traits controlled by each allele are both visible in the individual.


What is Co-dominant Alleles?

Co-dominant alleles are two different versions of a gene that are both fully expressed in a heterozygous individual. This means that both alleles contribute to the phenotype of the organism. An example of co-dominant alleles in humans is the ABO blood group system, where A and B alleles are co-dominant to each other.


How is it possible to have neither allele dominant?

In cases where neither allele is dominant, both alleles are expressed equally in the phenotype. This is known as codominance, where both alleles contribute to the phenotype without one overpowering the other. An example of this is in blood type inheritance, where the AB blood type is the result of codominance between the A and B alleles.
