What else can I help you with?
Which allele (gene) exhibits its trait only when it is paired with another allele in a genetic cross?
Recessive allele exhibits its trait only when paired with another recessive allele in a genetic cross.
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.
What is The only trait shared by all invertebrates?
having no backbone
Is red hair a race?
No, it's only a genetic human trait that is prevalent in some but not others.
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.
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 can a parent learn the risks of having a child with a genetic disorder?
A parent can learn the risks of having a child with a genetic disorder by looking at their own history. A genetic disorder is... da da da da! Genetic! so the traits of this disorder would be passed down through the generations. If both parents have family members with the trait or if the disorder is a dominant trait then there is a high chance of the disorder being passed down to the child. If the trait is recessive and only one parent has the genetic disorder in their family history then there are some pretty low chances of it being passed along to the child. Even if the trait is recessive, if both parents have the diorder in their history then there is about a 50% chance of the child having the disorder.
How might a scientist determine whether a trait is a sex-linked by observing the offspring of several genetic crosses?
no
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 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.
