Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
Yes, individuals who are heterozygous for a recessive allele but have a normal phenotype will not typically pass on the harmful recessive allele to their children unless their partner also carries the recessive allele. This is because the dominant allele masks the presence of the recessive allele.
What does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
Two alleles for a certain trait are passed to an individual. what terms refers to the trait that will show up in the individual?
The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
When the dominant allele does not completely mask the effect of the recessive allele in the heterozygote it is called polygenic dominance incomplete dominance dominance corecessive codominance?
When the dominant allele does not completely mask the effect of the recessive allele in the heterozygote, it is called incomplete dominance. In this case, both alleles contribute to the phenotype, resulting in an intermediate phenotype.
Why might a harmful allele persist in a population for many generations?
A harmful allele may persist in a population due to genetic drift, where chance events can lead to its continued presence. Additionally, if the allele is recessive or has a late-onset effect, it may not be selectively disadvantageous enough to be eliminated by natural selection. Finally, a harmful allele may also persist if it is linked to a beneficial allele in the genome, creating a genetic trade-off.
Why does selection act faster against a harmful dominant allele than a harmful recessive allele?
Selection acts faster against a harmful dominant allele because individuals with the allele will show the harmful trait, making them more likely to be removed from the population. In contrast, harmful recessive alleles are only expressed in homozygous individuals, making it harder for selection to act on them as carriers of the allele may not exhibit the harmful trait.
What is a dominant allele what is a recessive allele?
An allele that hide the effect of other allele is called dominant.Allele that is masked is called recessive .
What is a process that eliminated harmful allele from a gene pool?
negative selection.

What is an organism that is heterozygous for a harmful trait?
An example of an organism that is heterozygous for a harmful trait is a carrier of a genetic disease like sickle cell anemia. In this case, the individual has one copy of the normal allele and one copy of the disease-causing allele, which can lead to the manifestation of the disease in offspring if they inherit two copies of the harmful allele.
Is when one allele completely masks another?
This is called complete dominance, where one allele completely masks the expression of another allele in a heterozygous individual. The dominant allele is expressed phenotypically, while the recessive allele remains hidden.

The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.

What is a change in allele frequency that results from the migration of a small subgroup of a population called?
This is known as the founder effect, where a small subgroup establishes a new population with a different allele frequency compared to the original population.
