What is tessesive trait?

In genetics, a recessive trait is a characteristic that is only expressed when an individual has two copies of the recessive allele. This means that an individual must inherit two copies of the specific allele (one from each parent) in order for the recessive trait to be visibly manifested in the phenotype.


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.


How do scientist predict which genes an organism will inherit?

The scientist will produce a pedigree from information about the members of past and present generations, and will use that information to predict the probability that an offspring will inherit a specific (usually undesirable) trait.


What trait that may not show when an animal carries it but which can be passed on to its offspring and perhaps show there is called what kind of trait?

A trait that may not be visibly expressed in an animal but can be passed on to its offspring is called a "recessive trait." This trait is only observable when an organism has two copies of the gene responsible for it, one from each parent.


If an individual has the copies of a trait the same what is it called?

If an individual has two identical copies of a trait, it is called homozygous for that trait. This means that both copies of the gene are the same, whether they are dominant or recessive.

When is the only time a recessive trait appears on a organism?

A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.


Traits that typically will only be expressed in offspring if they inherit two copies of the genes for that trait is called what?

Recessive traits. This means that the trait is only expressed when an individual inherits two copies of the recessive allele for that trait, one from each parent.


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.

Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called Recessive traits. - Nikkkki


What is the definition of a discrete trait?

A discrete trait is a trait which doesn't have a range of phenotypes. For example, tongue rolling is a discrete trait as an individual can either roll their tongue or not roll their tongue. There is no phenotype between these two phenotypes.


Trait of an organism that can be masked by the dominant form of a trait?

A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.


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.


What is the likelihood that the offspring of individuals IV-3 and IV-4 will inherit the trait?

The likelihood that the offspring of individuals IV-3 and IV-4 will inherit the trait depends on the specific genetic inheritance pattern of the trait. If the trait is determined by a dominant gene, there is a 50 chance that the offspring will inherit the trait. If the trait is determined by a recessive gene, there is a 25 chance that the offspring will inherit the trait.


How can offspring inherit a recessive trait?

An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.

What kind of allele must an organism inherit in order for a recessive trait to show up?

Neither of the parents will be affected. There may not be any one with he disease in either of the parents families (or there might be). Since each parent is a carrier and has a 50/50 chance of passing one copy of the gene to each child 1/4 of the children will not get the gene, 1/2 will be carriers (1 copy) and 1/4 wil be affected (2 copies).
