A dominant gene will be expressed if paired with a recessive gene or with a dominant gene for the same trait. For example, the trait for brown eyes (BB) is dominant over blue eyes (bb) - thus an offspring Bb will express brown eyes, just as BB.

∙ 13y agodominant traits are not always more common or more likely to occur because you could be living on a small island that doesn't get visitors and almost everyone has this recessive trait the recessive trait would be more likely to occur when a baby is born

∙ 14y agothe alleles are always present, but the dominant isn't always present in the organism. to find the probability, you use a punnett square to see when the dominant allele shows up. when the dominants allele is present, the organism will take the trait of that allele.

∙ 12y agoSome are dominant while others are recessive. There can also be co-dominant traits though. It all really depends on what you are looking at. For example Gregor Mendel with his peas, wrinkled vs. round and yellow vs. green were simply dominant or recessive. But if you look at the flower snapdragon then you can have a red one and a white one and mix them together to get a pink one because both of the genes are dominant and therefore co-dominant.

∙ 11y agoIt only takes one copy of a dominant allele to produce an organism with the dominant phenotype. This means that homozygous dominant or heterozygous individuals will display the dominant trait.

∙ 13y agowhy do you think they're called dominant traits genius
^^very rude^^
Actually, some recessive traits are more common in a POPULATION.

What did mendel call the trait that always showed up?
Mendel called the trait that was always expressed the dominant trait.
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
Dominant
What are an individuals expressed traits called?
genotype
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.
What did mendel call the trait that always showed up?
Mendel called the trait that was always expressed the dominant trait.
What gene that is always expressed and will produce a trait?
The gene that is always expressed and will produces a trait is a genetic statistic. This statistic is what is created when the gene is dominant.
Not expressed when the dominant form of a trait is present?
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
A red-eyed fly mates with a blue-eyed fly. The offspring all have red eyes. What is the dominant trait?
A dominant trait, when present, is always expressed. So if the offspring of a red eyed and blue eyed mating are all red, then red must be dominant because it is the trait expressed.
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.
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What is the term for an expressed allele?
dominant trait
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is the dominant trait when a red-eyed fly mates with a blue-eyed fly resulting in offspring that all have red eyes?
A dominant trait, when present, is always expressed. So if the offspring of a red eyed and blue eyed mating are all red, then red must be dominant because it is the trait expressed.
