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 is it when each gamete gets one gene for each trait?
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.
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 does recessive mean as it relates to genes?
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.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
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.
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.

What is a trait that is expressed even if only one gene for that form of the trait is inherited?
A dominant trait is expressed even if only one gene for that trait is inherited. Dominant traits will mask the expression of recessive traits if both forms of the gene are present.
What is it when each gamete gets one gene for each trait?
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.
Will an offsping show a recessive trait if only one of its parents has the gene for that trait?
No
What gene won't display its trait in the prescience of a dominate trait?
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.
What is the difference between a single gene and a polygenics trait?
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.
What shows that alleles might combine?
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.
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 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.
