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?
Not always. Different chromosomal fragments travel different distances in electrophoresis due to their different lengths. Longer fragments are heavier and therefore travel shorter distances under the same electrical force.
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 is the hidden gene called?
The term "hidden gene" often refers to "silent mutations" or genes that are not expressed under normal conditions but can be activated under specific circumstances. In some contexts, it may also refer to "epigenetic" changes that silence or activate certain genes without altering the DNA sequence itself. Another interpretation could be "cryptic genes," which are present in the genome but not typically expressed or identified in standard analyses.
What type of cellular respiration do humans perform under normal circumstances?
"aerobic"
Dominant alleles are so called because under most circumstances they?
are phenotypically expressed. They are expressed in homozygous form and in heterozygotes with the recessive allele. Recessive alleles are only phenotypically expressed in homozygous form. Consider two alleles for flower color, A and a, where A is dominant and expressed as red, and a is recessive and expressed as white. There are only three diploid genotypes possible for these alleles: AA Aa and aa.However, because A is dominant, the following phenotypes will be expressed for the following genotypes:AA: redAa: redaa: white
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.

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?
Not always. Different chromosomal fragments travel different distances in electrophoresis due to their different lengths. Longer fragments are heavier and therefore travel shorter distances under the same electrical force.
Are the dominant traits always the most common in a population?
it is because that trait is more dominant. when a dominant and a recessive trait combine it is most likely that hte dominant trait will be expressed. it is only when a recessive trait combines with an another recassive trait that hte trait gets expressed(which is rare and not so commonly occuring)
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.

Is failure to appear a felony charge under all or any circumstances?
No. Not under "all or any circumstances."
