Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a recessive allele.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
Is albinism a dominat or reccesive trait?
Albinism is a recessive trait which will result in a lack of pigmentation in the skin eyes and hair. It occurs about 1 in every 17,000 people in the U.S.
Albinism is a recessive trait in humans that is controlled by a single gene how many recessive alleles must a person have to have albinism?
2
Is albinism a recessive trait or dominant?
Recessive. The trait will only show up if both parents have the gene recessively (aa). If the genetic make up is Aa or AA, there will be melanin production, meaning albinism is an aa gene only. Albinism is a recessive allele.
What combination of alleles could produce a trait controlled by a recessive allele?
recessive + recessive or tt
When will a trait controlled by a recessive allele be shown?
only when two recessive alleles are present
Are smile dimples controlled by a recessive allele?
Nope, the alleles for smile dimples are actually dominant, not recessive.
How can albinism in plants keep occurring if they cannot reproduce?
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Is cystic fibrosis controlled by a dominant allele or by a recessive allele?
It is controlled by a recessive allele. The gene encodes a chloride ion channel that is required to make sweat, mucus and a few other things. One copy of the gene is sufficient to prevent cystic fibrosis, and it is only when both copies are defective that the person would have the disease and show symptoms.
Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.
