AB blood is an example of what form of gene expression?
AB blood is an example of codominance in gene expression. In this case, both alleles A and B are expressed equally in the phenotype, resulting in the AB blood type. This occurs because neither allele is dominant over the other, allowing both to contribute to the blood group's characteristics.
Blood types in humans are an example of traits controlled by?
Multiple alleles
What is a synonum for gene expression?
Gene expression could also be known as gene transcription, as the process almost always involves transcribing genes into RNA and/or protein types.
What is the definition of constitutive gene expression and how does it differ from other types of gene regulation?
Constitutive gene expression refers to genes that are constantly active and produce proteins at a steady rate in a cell. This type of gene expression is not influenced by external factors or signals. In contrast, other types of gene regulation involve genes that are turned on or off in response to specific signals or conditions in the cell's environment.
What is a gene that has 3 or more alleles for a single trait?
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
What is an example of a single gene with multiple alleles?
An example of a single gene with multiple alleles is the ABO blood group gene. This gene has three main alleles: A, B, and O, which determine an individual's blood type. Different combinations of these alleles result in the four blood types: A, B, AB, and O.
What is a gene that has 4 alleles?
One example of a gene with four alleles is the ABO blood group gene, which determines human blood types. The gene has three main alleles: A, B, and O, with the A and B alleles being co-dominant and the O allele being recessive. However, the presence of additional alleles, such as those associated with rare subtypes (like Ax or Ay), can extend the total number of recognized alleles for this gene. This genetic variability contributes to the diversity of blood types in the population.
What is the lac operon in E. coli a classic example of?
gene expression occurring at transcription
What is The expression of a gene is called?
The expression of a gene is called the phenotype.
How a gene with multiple alleles can produce more than three phenotypes use blood as an example?
A gene with multiple alleles can produce more than three phenotypes because each allele can result in a different blood type. In the ABO blood group system, there are three alleles (IA, IB, i) that determine the presence of antigens on red blood cells, leading to four possible blood types (A, B, AB, O). The combination and expression of these alleles determine the individual's blood type phenotype.
What codes for protein in the process of gene expression?
In the process of gene expression, the gene codes for protein.
What does differential gene expression mean?
Differential gene expression refers to the phenomenon where the level of expression of a gene can vary between different cells, tissues, or organisms. This variability can lead to distinct phenotypic differences, such as the development of specialized cell types or response to environmental stimuli. Studying differential gene expression is important for understanding how genes function and how organisms develop and respond to their surroundings.
