When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
Which form of gene pair is expressed when both dominant and recessive are present?
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene

What is a person who has a dominant and one recessive copy of a disease gene?
A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.
Is Thomsen disease dominance or recessive?
its autosomal dominant
Is cystic fibrosis a dominant or co-dominant disorder?
It is autosomal recessive and it is not a disorder! Cystic Fibrosis is a disease.
If an individual expresses a dominant disease will the children always inherit the disease?
Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.
Is canavan disease dominant or ressesive?
I was doing a presentation on Canavan Disease and had a lot of trouble finding wether it was dominant or recessive. I found the answer and thought i should make it easier for others. Canavan Disease is recessive
