What else can I help you with?
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
What does it mean that an organism is homozygous recessive for a trait?
An organism that is homozygous recessive for a trait carries two copies of the recessive allele for that trait. This means that the individual will express the recessive trait because there is no dominant allele to mask its expression.
Do organisms that are purebred for a trait will express the same characteristics for many generations?
Yes, organisms that are purebred for a trait will generally express the same characteristics for many generations as long as there is no genetic mutation or environmental influence that causes a change in the trait. This is because purebred organisms have homozygous genotypes for that trait, resulting in consistent expression of the trait in offspring.
IS IT POSSIBLE TO HAVE A RECESSIVE TRAIT APPEAR IN OFFSPRING IF THE GENOTYPE IS HETEROZYGOUS?
No, a heterozygous genotype, which consists of one dominant and one recessive allele (e.g., Aa), will typically express the dominant trait, not the recessive one. However, if both parents are heterozygous (Aa), there's a possibility for offspring to inherit two recessive alleles (aa), which would express the recessive trait. Thus, while a heterozygous individual cannot express a recessive trait, such traits can appear in their offspring if the right allele combinations occur.
What is sense of homour?
A sense of humor is a specific trait in which someone can both appreciate humor and express humor.
What has a gene for a certain trait but does not express that trait itself?
recessive
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
Is childish a trait?
Yes. It actually is a character trait because it tells you about how someone is.

What is a person who has recessive allele for a trait but does not express that trait?
They would be considered a carrier. ------------------------------- More precisely a heterozygote. A carrier would imply that the recessive trait causes disease.
Would the genotypes AA and AA express a dominant trait?
yes.
What is a carrier and how does it affects heredity?
A carrier is somebody has has a specific gene trait but does NOT express it.
What is an organism that has different factors for a particular trait?
my science book tells me that it is phenotype
Does aguy like me if he tells me what he does and doesn't like in a girl?
if he names a trait that you have then yes
Do organisms that are purebred for a trait will express the same characteristics for many generations?

This is because purebred organisms have homozygous genotypes for that trait, resulting in consistent expression of the trait in offspring.
What is an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
