What does dominance refer to in genetics?
In genetics, dominance refers to the relationship between alleles, where one allele masks or suppresses the expression of another allele at the same gene locus. The dominant allele's traits are expressed in the phenotype, while the recessive allele's traits are hidden unless two copies are present. This concept is crucial in understanding inheritance patterns and phenotypic variations in organisms.
Is phenotype another name for allele?
No, phenotype and allele are different concepts in genetics. An allele refers to the specific form of a gene, while phenotype refers to the observable traits or characteristics of an organism resulting from the interaction of its genotype with the environment.
Why do allele frequencies always add to one?
Allele frequencies in a population refer to the proportion of each allele for a given gene among all alleles at that locus. Since all possible alleles at a locus contribute to the genetic makeup of that population, the sum of their frequencies must equal one, representing the entire genetic pool for that gene. This ensures that the distribution of alleles reflects the entirety of genetic variation available for that trait within the population.
What is AA gene?
The AA gene typically refers to a genetic variant associated with specific traits or conditions, often denoted in the context of single nucleotide polymorphisms (SNPs) or other genetic markers. The term can also refer to the "A" allele in a broader genetic context, particularly in studies related to population genetics or disease susceptibility. However, without a specific context, it's important to note that "AA gene" could refer to different genes or variants in various genetic studies.
Do alleles have to be the same trait for example Tt or can they have two traits combined for example Tb?
In classical genetics, alleles refer to different forms of the same gene that can result in different traits. An individual would not have an allele represented as "Tb" for example - instead, they may have "T" and "b" as separate alleles that influence different traits. Each allele typically represents a specific version of a gene that contributes to a particular characteristic.

What does a lower case letter of an allele refer mean?
A lower case letter for an allele typically indicates a recessive trait. In genetics, alleles are alternate forms of a gene that can produce different effects on an organism's phenotype. The convention of using lower case letters for recessive alleles helps distinguish them from dominant alleles, which are usually represented by capital letters.

How do you refer to a wave?
By it's frequency

What the meaning of genoytpe?
It is the set of genes that an individual has, or it can refer to what allele of a particular gene an individual has.
What is An organisms allele pairs?
An organism's allele pairs refer to the different forms of a gene present on each pair of homologous chromosomes. Each allele represents a variation of a particular gene and can be dominant or recessive. The combination of allele pairs determines an organism's genetic traits.
Which one does not belong Phenotype - genotype - allele?
Phenotype does not belong because it represents the physical characteristics or traits of an organism, whereas genotype and allele both refer to the genetic makeup of an organism.
What does the founder effect refer to?
Genetic drift. It is when a representative sample of emigrant alleles that break off from a larger population and travel to a new location do not represent a complete frequency of the parent populations alleles. They then vary from a little to greatly from the parent population. Deleterious recessive alleles can be expressed in this founder population in greater frequency sometimes. Look up the ' Quebec effect.
What does Frequency effects?
Frequency effects refer to how often a behavior occurs and the impact it has on learning or conditioning. Higher frequency of a behavior can lead to faster acquisition and stronger reinforcement. In cognitive psychology, frequency effects can also refer to how frequently a word or concept is encountered, affecting comprehension and memory.
