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.
An example of a trait you inherit from your parents is?
Eye color.
Boys can inherit an X-linked trait from their?
Father
What controls the trait children inherit?
the alleles from the parents
What is the name of the trait that an organism develops after its born?
Acquired Trait
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called?
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
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
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.

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 is meant by recessive trait when discussing genetics?
When discussing genetics, recessive trait refers to the fact that the offspring of two parents must inherit two copies of a gene to expose the trait. This would mean that both parents must be carriers of said gene in order for their offspring to show a recessive trait.
What is an organism with two genes for a trait called?
An organism with two like alleles for a trait is homozygous for that trait.
What term describes an individual with two copies of the same allele?
The individual with two of the same allele is "homozygous" for a trait.
Where the alleles for a given trait are inherit from?
The alleles for a given trait are inherited from an individual's parents.
How many recessive alleles for a trait must an organism inherit in order to show that trait?
Except in rare cases, you can only inherit one allele per parent per trait (for those of you that don't know, that's two alleles). A recessive trait will be shown if both alleles are for said recessive trait. If one of the alleles is for a dominant trait, then the dominant trait will show. Some genes are tied to environment and exposure to certain things, so a trait may be 'masked' for the duration of a person/organism's life, or at least until they are exposed to it. For example, an allergy to plastic would not be apparent in someone living in Africa unless by chance they came into contact with a plastic bucket, plastic hairbrush, etc., from, say, a visiting doctor from America.
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.
An example of a trait you inherit from your parents is?
Eye color.
