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.
Can a human pedigree be used to detect a recessive trait?
Yes, a human pedigree can be used to detect a recessive trait by tracking the inheritance pattern of the trait within a family. Patterns such as multiple affected siblings, skip generations, and consanguinity can help identify recessive trait inheritance. Pedigree analysis can reveal carriers of the trait even if they do not show symptoms.
When would a pedigree be better to use to deterimine the genotype of an individual instead of a testcross?
n genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply put, test crosses determine the genotype of an individual with a dominant phenotype.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
What chart tracks which family member has a certain trait?
A pedigree chart tracks the inheritance of specific traits within a family. It can be used to visually represent how a particular trait is passed down through generations and which family members exhibit the trait. This type of chart is commonly used in genetics to study patterns of inheritance.
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.

If the trait skips generations, it is likely recessive. Genetic testing can also help confirm the inheritance pattern of the trait.
How are phenotype used in pedigree analysis?
The pedigree will typically show one kind of trait and the affected members of a family. Take a look at if the trait is dominant or recessive first. Once you have that figured out,start to predict the genotypes of the individuals in the pedigree.

What does dominant pedigree means?
A dominant pedigree refers to a pattern of inheritance in which a dominant allele on a gene is expressed in the phenotype of an individual, masking the effects of a recessive allele. This results in the dominant trait being exhibited in individuals who inherit at least one copy of the dominant allele.
If curly hair (C) is a dominant trait what are the genotypes of the parents in the pedigree?
In a pedigree where curly hair (C) is a dominant trait, the genotypes of the parents can vary. If at least one parent has curly hair, their genotype could be either CC (homozygous dominant) or Cc (heterozygous). If both parents have straight hair (which is the recessive trait), their genotype must be cc. To determine the specific genotypes of the parents more accurately, you would need to analyze the phenotypes of their offspring in the pedigree.
To trace a trait through generations of family you can use a?
To trace a trait through generations of a family, you can use a pedigree chart. This diagram visually represents the family tree, showing the relationships between family members and the occurrence of specific traits or conditions. By mapping out the inheritance pattern, you can identify whether the trait is dominant, recessive, or linked to a particular gene. Pedigree charts are commonly used in genetics and medicine to understand hereditary patterns.
Is it true that a pedigree diagram is a simple genealogical diagram showing family members' relationships to each other and how a particular trait or disease has been inherited?
A pedigree is a chart that tracks which members of a family have a particular trait. The trait that a pedigree tracks can be almost anything. It can be eye color, hair color, or colorblindness. It can also track genetic disorders, such as cystic fibrosis, hemophilia, or sickle-cell disease.
How do you figure out if a trait is dominant or recessive without making an experiment?
You can determine if a trait is dominant or recessive by observing the inheritance pattern in a family. If individuals with the trait only have one copy of the allele and can pass it on to their offspring, the trait is likely dominant. If individuals need to have two copies of the allele to express the trait, it is likely recessive.
Is the hitch hiker's thumb the dominate trait?
the hitchhiker's thumb is the recessive trait. normal thumbs are dominant. i learned this in science class and i am doing a family pedigree on the hitchhiker's thumb.
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.
Scientist use a chart to study the inheritance pattern of a trait it is a what?
Scientists use a pedigree chart to study the inheritance pattern of a trait. This diagram illustrates the relationships within a family and shows how traits are passed from one generation to the next. By analyzing the chart, researchers can identify patterns of inheritance, such as dominant, recessive, or sex-linked traits. Pedigree charts are essential tools in genetics for understanding hereditary conditions and predicting genetic risks.
