No, each gene can influence multiple traits, a phenomenon known as pleiotropy. Additionally, traits are often governed by the interaction of multiple genes, making the relationship between genes and traits complex. Environmental factors also play a significant role in how genes express traits, further complicating this relationship.
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.
This is known as the law of segregation in genetics, which states that each parent donates one of two alleles for each gene to their offspring. As a result, each gamete (sperm or egg) receives only one gene for each trait. This process ensures genetic diversity and the random assortment of traits in offspring.
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.
A non-example of a dominant gene would be a recessive gene, which only expresses its trait when two copies are present (one from each parent). For instance, if the gene for blue eyes is recessive, a person would need to inherit the blue eye gene from both parents to express that trait. In contrast, a dominant gene, such as one for brown eyes, would be expressed even if only one copy is inherited.
A recessive gene is one that is only expressed if an individual has two copies of that gene. This means that the trait associated with the recessive gene is not visible unless an individual inherits two copies, one from each parent. If an individual inherits only one copy of a recessive gene, the dominant gene will be expressed instead.
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.
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.
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.

No
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
The manifestation of two traits or a whole new trait, whereas in examples where only each of the gene is present, the manifestation of one trait in either one.
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.
A recessive gene is one that is only expressed if an individual has two copies of that gene. This means that the trait associated with the recessive gene is not visible unless an individual inherits two copies, one from each parent. If an individual inherits only one copy of a recessive gene, the dominant gene will be expressed instead.
This is known as a dominant trait. Dominant traits require only one copy of the gene to be expressed in an individual. The presence of one dominant allele is sufficient to display the trait, even if the individual also carries a different allele for the same gene.
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.
