What type of alleles are expressed only if two identical copies exist on the homologs of the offspring?
Recessive alleles are expressed only when two identical copies exist on the homologs of the offspring. In this case, if an individual inherits two copies of the recessive allele, it will show the recessive trait.
What type of trait is only seen if its gene is present in both gametes that unite to start the life of a new organism?
Recessive trait. This type of trait is only expressed when the individual has two copies of the gene for that trait, one from each parent. If only one copy is present, the dominant trait will be expressed.
Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
What is true breeding?
Purebred organisms are the organisms in the off springs for many generations which have the same traitA true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring.
What example describes an inherited trait that cannot be determined by observing an individual?
A genetic trait that is inherited but not visually expressed, such as a recessive gene for a disease or a carrier status, cannot be determined by observing an individual without genetic testing. For example, an individual who carries a recessive gene for a genetic disorder may not show any symptoms themselves, but can pass on the gene to their offspring.
Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
What is a trait that needs two factors in order to be expressed?

The concept that one type of trait will be more likely to be seen in offspring is part of the principle of?
The concept that one type of trait will be more likely to be seen in offspring is part of the principle of inheritance, specifically known as Mendelian genetics or Mendel's laws of inheritance. These laws describe how traits are passed from parent to offspring through the transmission of genes.
What is arecessive trait?
A recessive trait is a genetic trait that is only expressed when an individual carries two copies of the gene responsible for that trait. It is masked by the presence of a dominant trait when an individual carries one copy of each type of gene.
What type of alleles are expressed only if two identical copies exist on the homolgs of the offspring?
Recessive because...

What describes the mating of organisms that have different homozygous alleles for a single trait?
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.

What is crossing recessive with dominant?
Crossing a recessive trait with a dominant trait involves breeding an organism that expresses the dominant phenotype with one that expresses the recessive phenotype. In genetics, the dominant trait will typically mask the expression of the recessive trait in the offspring. This can help determine the genotype of the dominant organism; if any offspring exhibit the recessive trait, the dominant parent must carry a recessive allele. This type of cross is often used in Mendelian genetics to study inheritance patterns.
