What else can I help you with?
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
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.
What is the physical trait that gets expressed by a gene pair?
the dominant gene
What is a set of genes that determine a trait?
A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.
What happens when 2 different allele s for the same trait are present?
if the two alleles are the same in the same box in the punnett square then that trait is expressed. when there is a double in a punnett square then that gene is always expressed
Can a single recessive gene can determine the nature of a trait?
Yes, a single recessive gene can determine the nature of a trait if it is expressed and not masked by a dominant gene. In cases where the individual inherits two copies of the recessive gene, the trait will be expressed.
Will a A trait controlled by a dominant gene be expressed even if the instructions of the corresponding gene in the other half of the pair are different?
Yes, if a trait is controlled by a dominant gene, it will be expressed regardless of the instructions of the corresponding gene in the other half of the pair. Dominant genes only require one copy to be expressed in the phenotype.
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.
What is recesive ginetic?
A recessive genetic trait is one that is expressed only when an individual carries two copies of the gene for that trait. If an individual carries one copy of the recessive gene and one copy of a dominant gene, the dominant gene will be expressed while the recessive gene remains hidden. This means that the trait associated with the recessive gene will only appear if both parents pass on a copy of the recessive gene to their child.
What is the form of gene that seems to have no impact on a trait in a heterozygous state?
A gene that shows no impact on a trait in a heterozygous state is called a recessive gene. In a heterozygous individual, the dominant gene will determine the trait expressed, while the recessive gene remains hidden.
Traits that are typically expressed even if an offspring inherits just one copy of a gene for the trait are called what traits?
Dominant trait due to doominant gene (as against recessive trait)
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.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
