At is a gene with two dominant alleles that are expressed at the same time?
Co-dominant or incomplete dominance situation.
What is the term that describes when both alleles show up equally?
homozygous dominant or recessive depending on what gene it is
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
What is the gene pair consit of dominant alleles or to two recessive alleles?
homozygous
What is homozygous-?
Every gene has a dominant and recessive allele, homozygous is just when a gene has either two dominant alleles or two recessive alleles.
The gene that is fully expressed when two different alleles are present is the?
Dominant alleles :) hope i helped
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
A dominant genetic disorder will be expressed if an individual has?
Two dominant alleles that cause the disorder.
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
At is a gene with two dominant alleles that are expressed at the same time?
Co-dominant or incomplete dominance situation.
Is a recessive gene expressed?
Ok, im assuming your question is "if two recessive alleles are present will the trait be expressed" A trait will be expressed if two alleles are recessive but it will not be the same representation as two dominant alleles. For example, T being a tall pea plant and t being a small pea plant. Two recessive alleles or, homozygous recessive, alleles The other option would be there is one dominant and one recessive, heterozygous, which would look like Tt. This would take on the trait of the dominant allele usually expressed by the capital letter. So this heterozygous plant would be tall.
When the alleles of a gene pair are expressed differently but neither is dominant to the other?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed.
What is the term that describes when both alleles show up equally?
homozygous dominant or recessive depending on what gene it is
What is meaning of alleles?
An allele is the different forms of a gene. For example the gene for eye colour has the alleles; brown, blue, green etc. In every person there are two alleles for every gene but both alleles are not always the same. They can be dominant and recessive; dominant alleles are expressed no matter what other allele is present, recessive alleles require both alleles to be the recessive one to be expressed. E.g. say B is the allele for brown eyes and b is the allele for blue eyes. Brown is dominant therefore if someone had Bb or BB they'd have brown eyes and if they had bb their eyes would be blue.
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
