What is the relationship between dominant and recessive allelse?
Dominant alleles are those that express their traits even when only one copy is present, while recessive alleles require two copies to manifest their traits. In a heterozygous individual (one dominant and one recessive allele), the dominant allele will mask the effect of the recessive allele. This relationship is fundamental in genetics, influencing inheritance patterns and phenotypic traits in organisms.
Which traits oberved were dominant and recessive?
In genetics, dominant traits are those that are expressed when an individual has one or two copies of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele and no dominant allele present. Dominant traits often mask recessive traits in heterozygous individuals.
Dominant and recessive traits?
In genetics, dominant traits are those that are expressed in an individual's phenotype when only one copy of the allele is present, while recessive traits require two copies of the allele to be expressed. Dominant alleles are represented by a capital letter (e.g., 'A'), while recessive alleles are represented by a lowercase letter (e.g., 'a'). The expression of dominant or recessive traits follows Mendel's laws of inheritance.
What Dominant traits tend to be observed more frequently because?
Dominant traits tend to be observed more frequently because they only require one copy of the dominant allele to manifest in an individual, unlike recessive traits that require two copies. This means that if a dominant allele is present, it will express itself regardless of the other allele inherited. Additionally, dominant traits can often confer advantages in survival or reproduction, leading to higher frequencies of these traits in a population over time.
Comapre and contrast dominant and recessive traits?
Dominant traits are characterized by a single copy of a gene being sufficient to express a certain trait, whereas recessive traits require two copies of the gene (one from each parent) for the trait to be observed. Dominant traits typically mask the expression of recessive traits when both are present.

Is Recessive alleles the traits visible in the F1 generation of true-breeding organisms?
Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
Why does an organism have one factor for a dominant trait and one factor for a recessive trait?
Organisms have two factors (alleles) for a trait because they inherit one from each parent. Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when both alleles are recessive. This is known as Mendelian inheritance.
State Mendel's principle of dominance?
Only the dominant trait can be seen in an organism that is hybrid for a pair of contrasting traits

Are curly ears a dominant or recessive traits?
its a dominant trait because it covers up your recessive trait so only dominant shows :)

Dominant traits typically mask the expression of recessive traits when both are present.
What is an autosomal dominant trait?
An autosomal dominant trait is a characteristic that is determined by a dominant gene located on one of the non-sex chromosomes (autosomes). This means that only one copy of the dominant allele is needed for the trait to be expressed in an individual. Autosomal dominant traits will appear in each generation of a family with affected individuals.
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Does a dominant trait appear in the first generation?
Yes, a dominant trait will appear in the first generation if one of the parents carries the dominant allele. Dominant traits only need one copy of the allele to be expressed.
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called?
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called Recessive traits. - Nikkkki
