What is a small piece of DNA that tells a cell how to express a trait?
EleanorJohnsongp7905
DNA uses chromosomes 23 from your mom, and 23 from your dad. (46 together). If both your parents have brown eyes, there's a big chance of getting brown eyes.If both your parents have brown eyes and you get blue eyes that is a ressesive trait.

What does it mean that an organism is homozygous recessive for a trait?
An organism that is homozygous recessive for a trait carries two copies of the recessive allele for that trait. This means that the individual will express the recessive trait because there is no dominant allele to mask its expression.
Do organisms that are purebred for a trait will express the same characteristics for many generations?
Yes, organisms that are purebred for a trait will generally express the same characteristics for many generations as long as there is no genetic mutation or environmental influence that causes a change in the trait. This is because purebred organisms have homozygous genotypes for that trait, resulting in consistent expression of the trait in offspring.
What is sense of homour?
A sense of humor is a specific trait in which someone can both appreciate humor and express humor.
What is a protective trait?
A hummingbird does not specifically have one protective trait, but the way it can avoid predators is through its speed and small size. They are very agile.
What does it mean that an organism is homozygous dominant for a trait?
If an organism is homozygous dominant for a trait, it means that it has two identical dominant alleles for that specific trait. This suggests that the organism will express the dominant trait in its phenotype.
What has a gene for a certain trait but does not express that trait itself?
recessive
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
Is childish a trait?
Yes. It actually is a character trait because it tells you about how someone is.
What does it mean that an organism is homozygous recessive for a trait?
An organism that is homozygous recessive for a trait carries two copies of the recessive allele for that trait. This means that the individual will express the recessive trait because there is no dominant allele to mask its expression.
What is a person who has recessive allele for a trait but does not express that trait?
They would be considered a carrier. ------------------------------- More precisely a heterozygote. A carrier would imply that the recessive trait causes disease.
Would the genotypes AA and AA express a dominant trait?
yes.
What is a carrier and how does it affects heredity?
A carrier is somebody has has a specific gene trait but does NOT express it.
Do organisms that are purebred for a trait will express the same characteristics for many generations?
Yes, organisms that are purebred for a trait will generally express the same characteristics for many generations as long as there is no genetic mutation or environmental influence that causes a change in the trait. This is because purebred organisms have homozygous genotypes for that trait, resulting in consistent expression of the trait in offspring.
What is an organism that has different factors for a particular trait?
my science book tells me that it is phenotype
Does aguy like me if he tells me what he does and doesn't like in a girl?
if he names a trait that you have then yes
What is an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
Which of these is a gene that does not express itself and is concealed by the presence of another gene of the same trait?
A recessive gene is a gene that does not express itself in the presence of a dominant gene of the same trait. When an individual inherits two recessive genes for a trait, the recessive gene will be expressed.
