A recessive trait is the opposite of a dominant trait. A dominant trait is the trait that overpowers another trait- represented by a capital letter. The recessive trait is the trait that is weaker, and being overpowered- represented by a lowercase letter. For example, if one person had a recessive trait for detached earlobes, it would be represented as " aa ",. If someone had a dominant trait for attached earlobes (meaning they had free earlobes), it would be represented as "AA"or " Aa "

∙ 16y agoA person has two sets of genes, one from the mother and the other from the father. One is represented at the dominant gene and the other is the recessive gene. The recessive gene is the one that is not expressed in the phenotype but might be expressed in the children.

∙ 13y agoA recessive trait is one that is dominated by a dominant trait. An example would be a plant that has a tall dominate trait. Say a short and tall plant mate. The tall plant would pass on it's short traits, or tt, the tall plant would pass on it's traits, TT, if one t and one T are passed on making an offspring with genes Tt. Since the tall trait is dominate, the offspring's dominate trait T will overpower the recessive trait t.

∙ 11y agoIn DNA there are two types of a specific trait: recessive and dominant. You gain these traits from your mother and father. If the dominant trait is present, it always appears; even if the recessive trait is also present. It is easier to comprehend with an example.
The trait of blue eyes (we will write this as bb) is always recessive. The trait of brown eyes is dominant( we will write this as BB). If a person has brown eyes they can have trait combination of either Bb or BB. Even though the recessive trait is present in the first possible combo the dominant trait appears because it is also there. If a person has blue eyes they can only have the trait combo of bb. Let's say these two people are your parents. Your mother having brown eyes with the combo Bb and your father having blue eyes (bb). Your father will have to pass on the blue eyed gene because that is all he has. Your mother on the other hand has a 50% chance to pass on the brown eyed gene and 50% chance to pass on the blue eyed gene. If she does pass on the blue eyed gene then you would have the pair bb therefore resulting in blue eyes. Your mother didn't just mystically create the recessive blue eyed gene; it was passed on to her. Some one of her bloodline had blue eyes before her and the blue eyed gene was passed on generation to generation ultimately resulting in your blue eyes. (The case is the same with your father.)

What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
Why is it not necessary when the dominant and recessive traits are known to use the term homozygous when referring to the genotype of an individual that has a recessive phenotype?
An organism with a recessive allele from a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
A genetic trait which is present but unseen in an individual is called a trait?
Recessive For example, brown eyes (B) are dominant, blue eyes (b) are recessive. BB = brown Bb = brown bb = blue In the Bb genotype, the blue eyed gene is present, but the brown eyed gene is dominant, and show as the phenotype
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
YES ALWAYS!!! Even if you have for example, Aa (A being the dominant allele and a being the recessive allele) that trait will always be dominant!
Which term mean the state of having two identical alleles for the same trait?
Homozygous.
What does recessive mean in genetic term?
Recessive is the opposite of dominate, not as powerful of an influence on whether or not it will become the chosen trait on a punnett square.
What is the medical term meaning a trait that seems to recede into the background?
recessive traitThe Trait the seems to recede in the background in first-generation offspring is the recessive trait
What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
What term describes an individual that has a dominant and a recessive allele for a trait?
Heterozygous
What in term of applied to the trait that is expressed irregardless of the second allele?
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
Why is it not necessary when the dominant and recessive traits are known to use the term homozygous when referring to the genotype of an individual that has a recessive phenotype?
An organism with a recessive allele from a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
A genetic trait which is present but unseen in an individual is called a trait?
Recessive For example, brown eyes (B) are dominant, blue eyes (b) are recessive. BB = brown Bb = brown bb = blue In the Bb genotype, the blue eyed gene is present, but the brown eyed gene is dominant, and show as the phenotype
What is the term used to refer to an organism that has two indentical alleles for the particular trait?
The term used to refer to an organism that has two indentical alleles for the particular trait is homozygous. A trait could be homozygous dominant (TT), homozygous recessive (tt), or homozygous for incomplete dominance (rr).
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What is a recessive genes?
Recessive is a relative term used to describe the relationship to another allele termed the dominant allele. That traits of the recessive allele will only be shown if the person has two copies of the recessive allele. If a dominant allele is present, then the recessive trait will not be shown.
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
YES ALWAYS!!! Even if you have for example, Aa (A being the dominant allele and a being the recessive allele) that trait will always be dominant!
What is the medical term meaning developmental abnormality inherited as a recessive trait that is caused by excessive androgen secretion from the adrenal cortex of the female is called?
congential adrenal hyperplasia
