What one allele of a gene masks the presence of the other allele what form can be seen in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
Can a positive and o negative be full siblings?
Yes - but both of the parents would have needed at least one O allele and one Rh negative allele. If either parent was homozygous AA or OO (or homozygous Rh positive), then this would not be possible.
When one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
Are double first cousins 1st degree relatives?
Yes, double first cousins are considered first-degree relatives. This occurs when two siblings from one family each marry two siblings from another family, resulting in their children sharing both sets of grandparents. As a result, double first cousins have a closer genetic relationship than regular first cousins, sharing about 25% of their DNA, similar to that of half-siblings.
What is the largest number of siblings of one family married to siblings of another family?
"7 wives for 7 brothers."
Who was important to houdini?
His family he was one of seven siblings
What conclusion about your genotype is evident if one of your siblings but neither parent shows the recessive trait?
If one of your siblings shows the recessive trait but neither parent does, it suggests that both parents are carriers of the recessive allele. This means that you and your unaffected sibling have a 25% chance of inheriting two copies of the recessive allele, resulting in the recessive trait expression.
In one allele is dominant to a recessive allele?
In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.
You are positive n your mom is negative not sure what your dad is but your old brother n sister is negative can they be your full sister n brother or only half?
Upon conception, you receive an allele from your mother and one from your father. Yes these could be your full brother and sister because your father could be positive with a recessive negative allele and you could've received a positive from him whereas your siblings could've received the negative allele from him. You and your siblings can only get a negative allele from your mom because her two are negative.
When one allele of a gene masks the presence of the allele what form can be seen in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.

What are Cross Siblings?
Cross siblings refer to the children of two siblings from different families, specifically when one sibling from one family marries a sibling from another family. This creates a familial bond between the two families through the marriage of their siblings. For example, if a brother marries a sister from another family, their children are considered cross siblings to each other. This term highlights the interconnectedness of extended families through such relationships.
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).
How many siblings does floella Benjamin have?
Floella Benjamin has three siblings. She is the youngest of four children in her family. Her siblings include two sisters and one brother.
