Dominant alleles are expressed when an individual has at least one copy of the dominant allele in their genotype. This means that even if there is a recessive allele present, the dominant allele will be the one observed in the phenotype. Dominant alleles mask the expression of recessive alleles when they are both present in an individual's genetic makeup.

Do all versions of each gene always get expressed in an organism?
No, not all versions of each gene are always expressed in an organism. Gene expression can be regulated by various mechanisms, resulting in only certain versions or alleles of a gene being expressed under specific conditions or in specific cell types. This regulation ensures that the organism can respond to its environment and develop properly.
Do dominant alleles move farther in electrophoresis?
In general, dominant alleles do not necessarily move farther in electrophoresis compared to recessive alleles. The distance DNA fragments move during electrophoresis is based on their size and charge, not on their dominance or recessiveness.
What is a substance that carries electricity under certain circumstances but not under other circumstances called?
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
What type of cellular respiration do humans perform under normal circumstances?
"aerobic"
Why do some people have the same skin colour as their parent and others skin colour different from their parent?
it depends on your gene. there are dominant and recessive gene present. and for skin colour, bright colour are dominant over dark colour. if the both the parent are bright skin colour but the children is dark skin colour. there are possibilities where the recessive gene present in one or both parent. under certain circumstances the recessive gene will show its trait instead of the dominant gene. that's why some parent skin colour is different from the childrens' skin colour
Dominant alleles are so called because under most circumstances they?
are expressed, or "dominate," over recessive alleles in determining a specific trait in an organism's phenotype. This means that when an individual possesses at least one copy of the dominant allele, the trait associated with that allele will be visible.
What is the difference between a dominant and recessive allele?
Dominant is an allele that can be expressed in a heterozygous individual (ie. Bb) or homozygous dominant (ie. BB). Recessive on other hand are traits that will only be expressed in a homozygous recessive (ie. bb) condition. Under normal circumstances, dominant alleles are the ones expressed in the phenotype, while the recessive allele is not. For example (an extremely simplified example) an heterozygous individual for eye color. (genotype Bb), has one dominant allele, 'B', and one recessive allele, 'b'. Given that B is for brown eyes, and b is for blue eyes, that individual's phenotype would be expressed as brown eyes (and be recessive for blue eyes). Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
Do all versions of each gene always get expressed in an organism?
No, not all versions of each gene are always expressed in an organism. Gene expression can be regulated by various mechanisms, resulting in only certain versions or alleles of a gene being expressed under specific conditions or in specific cell types. This regulation ensures that the organism can respond to its environment and develop properly.
Under what condition is a single recessive allele expressed in a male?
A single recessive allele will be expressed in a male if he inherits that allele on his only X chromosome, as males have one X and one Y chromosome. This is because the presence of the recessive allele on the X chromosome has no dominant allele to mask its expression.
Do dominant alleles move farther in electrophoresis?
In general, dominant alleles do not necessarily move farther in electrophoresis compared to recessive alleles. The distance DNA fragments move during electrophoresis is based on their size and charge, not on their dominance or recessiveness.
Are the dominant traits always the most common in a population?
No, dominant traits are not always the most common in a population. Dominant traits refer to the expression of a particular gene over another, but the frequency of a trait in a population is determined by factors like genetic variation and environmental influences.
What is a substance that carries electricity under circumstances but not under other circumstances is called?
A substance that carries electricity under certain circumstances but not under others is called a semiconductor.
