What else can I help you with?
Is the trait being studied in the pedigree recessive or dominant?
This cannot be determined solely from a pedigree without additional information. The inheritance pattern of a trait can be deduced from the way it is passed down within a family and how it appears in the pedigree. Dominant traits will typically appear in every generation, while recessive traits may skip generations.
When using a pedigree chart you can distinguish between recessive and dominant traits because?
The two most straight forward ways are: - If both parents have the trait, and one of their children does not, it must be recessive. - If neither parent has the trait, and one of their children does, it must be dominant.
What feature of a pedigree would allow one to conclude that the disorder was caused by a dominant allele?
If the disorder is caused by a dominant allele, you would expect to see affected individuals in every generation of the pedigree, as it only takes one copy of the dominant allele to express the disorder. Additionally, affected individuals would have at least one affected parent.
Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
Is a dominant trait seen in the first generation or the second generation?
Dominant traits tend to manifest whenever they are inherited. The real question is, "When do you see recessive traits?" Traits are coded in genes. We all inherit genes from both of our parents. If the dominant trait is capital Y and the recessive trait is lowercase y we can calculate the odds fairly easily. There are only four combinations that can be inherited from one pair of parents: YY, Yy, yY, and yy (this is usually visualized using a "punnet square"). Only in the case of both inherited traits being lowercase y will we see the recessive trait. Otherwise, we will usually see the dominant trait.

How do you know from a pedigree diagram if a trait is dominant or resessive?
If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait. Dominant traits are usually expressed in every generation, while recessive traits can "hide" and reappear later.
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
How can one determine whether a pedigree trait is dominant or recessive?
One can determine whether a pedigree trait is dominant or recessive by observing how the trait is passed down through generations. If the trait appears in every generation, it is likely dominant. If the trait skips generations, it is likely recessive. Genetic testing can also help confirm the inheritance pattern of the trait.

In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
What was the radio of dominant to recessive phenotype in the F2 generation of Mendel's experiment?
The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the recessive trait.
How does a genetic trait appear every generation and what is it considered?
A trait like this must be homozygous dominate.
What was the ratio of dominant of recessive phenotypes in the F2 generation of Mendel's experiments?
The traits were recessive.
