What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
Genes that are not expressed if a dominant gene is present are called?
Recessive genes. These genes are only observed when an individual inherits two copies of the recessive allele.
A trait which results from two dominant genes is called?
It would depend on if the dominant genes are the same or different. Say the dominant alleles were different. In this case, they are co-dominant. If they are the same and both dominant homosytus.
What are the two types of alleles traits?
The two types of alleles for traits are dominant alleles and recessive alleles. Dominant alleles are expressed when at least one copy is present, while recessive alleles are only expressed when two copies are present.
What kind of trait is present when many different genes different genes control a single trait such as skin color?
Polygenic trait.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What trait is expressed when two different genes for the same trait are present?
dominant
What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
What genes are expressed even when present on only one chromosome?
dominant genes
Genes that are not expressed if a dominant gene is present are called?
Recessive genes. These genes are only observed when an individual inherits two copies of the recessive allele.
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
A gene that is not expressed when paired with a dominant allele is called?
A recessive gene. These genes are masked by dominant genes when they are present together in an individual's genetic makeup.
Genes that prevent the other gene from showing traits are called?
Dominant genes. Dominant genes are always expressed in an organism's phenotype when present, masking the expression of recessive genes.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
Are Genes present in heterochromatin readily expressed?
No. Heterochromatic regions of DNA are not readily expressed as they are densely packaged. Some of these regions do not code for genes at all.
Why are some genes are called dominant?
cause they can fool bi**
What are the different forms of a gene either dominant or recessive?
Genes can exist in different forms called alleles. Dominant alleles are expressed when present, masking the effects of recessive alleles. Recessive alleles are only expressed when two copies are present, one from each parent. This results in a wide range of possible genetic combinations and expressions.
