How many dominant alleles must be present in order to show the dominant phenotype?
Only one dominant allele is needed to display the dominant phenotype. Dominant alleles are expressed when present, masking the effect of recessive alleles.
What are inactive alleles?
Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.
What alleles will be expressed in your phenotype?
The alleles that will be expressed in your phenotype are the ones that are dominant and determine your physical traits. These dominant alleles will be visible in your appearance, while recessive alleles may be present in your genetic makeup but not visibly expressed.
Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
What is the physical result of a combination of alleles?
The physical result of a combination of alleles is known as the phenotype, which refers to the physical characteristics or traits of an organism. Different combinations of alleles can lead to variations in the phenotype, such as eye color, height, or hair texture.
An individual's description of that organisms particular combination of alleles is known as what?
A Phenotype
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.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
How many dominant alleles must be present in order to show the dominant phenotype?
Only one dominant allele is needed to display the dominant phenotype. Dominant alleles are expressed when present, masking the effect of recessive alleles.
In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
What are inactive alleles?
Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.
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
What are the two alleles that control the appearance of a trait?
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
Can two organisms have the same phenotype and a different genotype?
Yes,if one has two dominant alleles and other has a dominant and a recessive allele
What is a phenotype-?
A phenotype is the physical trait or feature of an organism that is the effect of a particular genotype. Flower color of snapdragons is one example of a phenotype, and the color is determined by which alleles comprise the genotype. Plants that are homozygous for the flower color alleles are either white or red. Heterozygous snapdragons are pink.
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.
Do alleles control phenotype?
Yes, alleles are variations of a gene that can affect the phenotype of an organism. The combination of alleles an individual carries determines specific traits or characteristics that are expressed.
