Why does a dominant trait appear in every generation of a pedigree?
A dominant trait appears in every generation of a pedigree because it is expressed when at least one copy of the dominant allele is present. This means that even if an individual carries only one dominant allele (heterozygous), the trait will be observable. As a result, dominant traits can be passed from affected parents to their offspring, making them visible in each generation. In contrast, recessive traits require two copies of the recessive allele to be expressed, so they may skip generations.
Why are two recessive alleles needed for a recesssive trait to be shown?
bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
Does recessive allele is expressed if there is no dominant allele present?
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.

When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
Is it possible to have a dominate recessive trait?
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
Are curly ears a dominant or recessive traits?
its a dominant trait because it covers up your recessive trait so only dominant shows :)

Is turners recessive or dominant?
It is neither recessive nor dominant because it is a chromosomal disorder and not just a problem present in a single gene.
Does recessive allele is expressed if there is no dominant allele present?
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
How is dominant trait and recessive trait related?
They are related to each other because whether they are dominant or recessive they are both homozygous, meaning the same. They can either be homozygous dominant or homozygous recessive. If they are heterozygous then they are different because it contains one dominant and one recessive allele each. EX: AA=homozygous dominant allele aa=homozygous recessive allele Aa=heterozygous allele
What gene will exhibit its traits even in a prensesce of a recessive gene?
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
Why are some genes alleles dominant and recessive?
Genes have dominant and recessive alleles because of the way they interact with each other. Dominant alleles are expressed over recessive alleles because they carry instructions that override the instructions of the recessive allele. This dominance is determined by the specific genetic makeup and interactions within an organism.
