Alleles that have more influence in determining traits are?
Dominant alleles are more influential in determining traits because they will be expressed even if only one copy is present. Conversely, recessive alleles are less influential as they will only be expressed if two copies are present.
Does a phenotype refer to the recessive alleles of an individual?
No, a phenotype refers to the observable traits or characteristics of an individual, which result from the interaction of its genotype (the genetic makeup, including both dominant and recessive alleles) with the environment. Recessive alleles can influence phenotype, but they do so only when two copies are present, as their effects are masked by dominant alleles. Therefore, a phenotype encompasses all expressed traits, not just those linked to recessive alleles.
What the 2 alleles are that control a specific characteristic?
The two alleles that control a specific characteristic are typically referred to as the dominant allele and the recessive allele. The dominant allele is expressed in the phenotype when present with a recessive allele, while the recessive allele is only expressed when two copies are present.
Can you determine whether an allele is dominant or rescessive on the basis of the ratio of the phenotypes in the population?
No, the determination of whether an allele is dominant or recessive is based on the inheritance pattern of the traits. Dominant alleles are expressed in the phenotype even if only one copy is present, while recessive alleles are only expressed when two copies are present. Phenotype ratios in a population can hint at the presence of dominant or recessive traits but do not definitively determine the dominance relationship of an allele.
What does it mean that CF is a recessive gene?
The phenotype associated with a recessive gene is only expressed when two copies of the gene are present. For example, if a person has both a recessive allele and a dominant allele for CF, the person does not have CF. The person only has CF if he/she has two copies of the recessive allele.
Alleles that have more influence in determining traits are?
Dominant alleles are more influential in determining traits because they will be expressed even if only one copy is present. Conversely, recessive alleles are less influential as they will only be expressed if two copies are present.
Which type of gene or gene combination can be present in a generation without affecting phenotype?
A recessive gene or gene combination can be present in a generation without affecting the phenotype if it is masked by a dominant gene. This means that the trait associated with the recessive gene will only be expressed if an individual inherits two copies of the recessive gene.

What is the ONLY genotype that can produce a recessive phenotype?
Only a homozygous recessive individual will have the phenotype created by two recessive alleles.Since the term produce might indicate the production of offspring parents that can only produce offspring with a recessive phenotype must both have homozygous recessive genotypes.
Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
Why is a persons phenotype harder to predict than a persons genotype?
Because peoples appearances changes as their body changes.
What does it mean that CF is a recessive gene?
The phenotype associated with a recessive gene is only expressed when two copies of the gene are present. For example, if a person has both a recessive allele and a dominant allele for CF, the person does not have CF. The person only has CF if he/she has two copies of the recessive allele.
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.
When is a recessive allele for a trait expressed in the phenotype of an dividual?
A recessive allele for a trait is expressed in the phenotype of an individual only when the individual is homozygous for that allele, meaning it has two copies of the recessive allele (one from each parent). If the individual has at least one dominant allele for that trait, the dominant trait will be expressed instead. Therefore, the presence of the recessive phenotype is only visible when both alleles are recessive.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
