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?

It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.

What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
How do you use dominant allele in a sentence'?
The dominant allele overpowers a recessive allele, therefore when the two are combined (heterozygous) the phenotype of the organism becomes whatever the dominant allele represents.
How can a lethal allele continue to be present in a gene pool even when they are selected against?
A harmful recessive allele remains in the population because both homozygous dominant and heterozygous genotypes produce the dominant, healthy phenotype. So the heterozygous genotype keeps the harmful recessive allele in the population.
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?
That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.

In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.

Why do we call some alleles dominant?
because it dominates the phenotype
What is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
