When offspring show a blend of the parents traits one allele is dominant over the other?

The results in the offspring hinge on the genetic make up of the parents. Each expressed trait is either the result of a dominant or recessive phenotype. The relative dominance or recessiveness of the alleles doesn't change only the rate at which they are expressed based on the allele present for each obseerved trait in the
parents.

Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Are recessive traits are always shown in an organism offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
What is the stronger gene for a trait always shows up in the offspring?
Yes, the dominant allele, if present, always overpowers the recessive one. There are exceptions though, when there are two different dominant alleles. These show in the form of co-dominance (two dominant traits that blend) and incomplete dominance (two dominant traits that both appear).
What gene will exhibit its traits even in a prensesce of a recessive gene?
The dominant allele
What happens when an allele is dominate or recessive?
Well, a dominant allele carries dominant traits from parents to offspring. An example of a dominant trait is brown hair and brown eyes because these traits are most likely to show up on a human than a recessive allele. A recessive allele may carry a recessive trait from parents to offspring such as blonde hair and blue eyes, these are uncommon because they are recessive traits.

For a codominant traiit do the offspring of identical parents always look like the parent why?
No, the offspring of identical parents would not always look like the parents because everyone has dominant and recessive traits, where the recessive traits do not show but is still in DNA. That said, recessive traits not shown in parents can be passed on as dominant traits to offspring - making offspring not always identical to its parents. (this is also called genetic variation)
Why is it important for an offspring to inherit the traits from its parents?
Offspring must inherit traits from its parents because it parents contained genes that were dominant and survived. the genes passed from parent to offspring are important because they are the dominant genes of survival. they passed of survival genes to help their offspring live longer.

A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.

Which of the following situations is most usual for a dominant allele that results in severe effects in the offspring?
The trait occurs by mutation.
What is contributing allele?
A contributing allele is a dominant allele which adds to the phenotype (the characteristics or traits of an organism).
What does it mean to have a dominant trait?
In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.
What gene will exhibit its traits even in a prensesce of a recessive gene?
The dominant allele
What is non-mendelian traits?
A trait with no clearly dominant allele.
