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 red hair a race?
No, it's only a genetic human trait that is prevalent in some but not others.
What is The only trait shared by all invertebrates?
having no backbone
What is arecessive trait?
A recessive trait is a genetic trait that is only expressed when an individual carries two copies of the gene responsible for that trait. It is masked by the presence of a dominant trait when an individual carries one copy of each type of gene.
Natural selection can only act upon a certain trait if the trait is?
Heritable, meaning that it can be passed down from one generation to the next through genetic inheritance. Without a genetic basis, natural selection would not be able to change the frequency of that trait in a population over time.
How can a parent learn the risks of having a child with a genetic disorder?
Parents can consult with a genetic counselor or a medical genetics specialist to understand the risks associated with having a child with a genetic disorder. These healthcare professionals can provide information on the family's medical history, conduct relevant tests, and offer guidance on available options for managing and mitigating risks. Additionally, online resources from reputable organizations like the National Institutes of Health or genetic support groups can also provide valuable information.
Why do some people have only 1 kidney?
Some people may have only one kidney for several reasons, such as having a diseased or injured kidney removed, or donating a kidney to someone in a kidney transplant, or probably less likely might be that they were just born with only one.
How might a scientist determine whether a trait is a sex-linked by observing the offspring of several genetic crosses?
no
A dog breeder can determine that the sudden appearance of hairlessness in one of the puppies is a mutation if the dog?
exhibits a new, unexpected trait not seen in either parent. The hairlessness trait is not present in the genetic makeup of the parents, suggesting it arose from a sudden genetic change. By observing this distinct trait only in one offspring, the breeder can confirm it as a mutation.
Is curved pinky dominant or recessive?
The trait of having a curved pinky is typically a dominant trait, meaning that it only requires one copy of the gene to be expressed. However, there may be other genetic or environmental factors that can influence the shape of a person's pinky finger.
Does the kidney loses half its essence if one of them is removed?
The remaining kidney actually picks up a lot of the workload of the removed kidney. That doesn't mean all of it, but it does compensate for it, which is why having only one kidney can take years off of your life, as the remaining kidney is having to work so much harder.
A genetic trait expressed in a person who has only one copy of the gene associated with the trait?
This is known as a dominant trait. Dominant traits require only one copy of the gene to be expressed in an individual. The presence of one dominant allele is sufficient to display the trait, even if the individual also carries a different allele for the same gene.
