What are some environmental factors that can influence that PTC taster phenotypes?
Environmental factors that can influence PTC taster phenotypes include dietary habits, particularly the consumption of certain bitter compounds found in plants, which may affect the expression of taste receptors. Additionally, geographic location and the availability of specific foods can impact the prevalence of taster or non-taster alleles in a population. Other factors, such as cultural practices and exposure to environmental toxins, may also play a role in shaping the expression of PTC tasting ability.
Is angel man recessive or dominant?
recessive
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
Is the trait for bleeder's disease dominant or recessive?
Recessive
What makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
Is the ability to taste PTC paper determined by a dominant gene?
Yes, the ability to taste PTC paper is determined by a dominant gene. If an individual inherits the dominant allele for tasting PTC, they will be able to taste it. If they inherit two recessive alleles, they will not be able to taste it.
Can two people who CANT taste PTC have children who can?
Yes, two people who cannot taste PTC (phenylthiocarbamide) can have children who can taste it. This is because the ability to taste PTC is a genetic trait influenced by a dominant allele. If both parents are homozygous recessive for the PTC tasting gene (tt), they will not be able to taste it, but if they carry a recessive allele (t) and a dominant one (T), there's a possibility of passing the dominant allele to their children, resulting in offspring who can taste PTC.

What can be dominant or recessive?
Alleles can be dominant or recessive
What could be the possible genotype of those that have the PTC trait?
The PTC trait is autosomal dominant so an individual with the trait could be homozygous dominant or heterozygous.
Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
How do you xxplain dominant and recessive?
Recessive
Is AAA recessive or dominant?
recessive
Which form of gene pair is expressed when both dominant and recessive are present?
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
