Do organisms that are purebred for a trait will express the same characteristics for many generations?

it depends if both parent are pure bread. if they are then they will be for that generation of offspring but if the other parent isn't then no.

What is DNA and how does it express itself in outward characteristics?

What is the expression of a gene?
Genes basically express proteins that are the organisms phenotype; the collection of the physiological and behavioral traits of an organism.
Do obligate anaerobes express superoxide dismutase?
No, obligate anaerobes do not express superoxide dismutase. This is because these organisms do not encounter oxygen in their natural environment and therefore do not need enzymes to detoxify reactive oxygen species like superoxide.
How do restriction enzymes help make recombinant DNA and transgenic organisms?
Restriction enzymes take apart the DNA in a certain area and allow for a plasmid to be inserted within the gap that is created. Restriction enzyme use is basically the same for both the production of recombinant DNA and for transgenic organisms since an organism can synthesize the DNA that has been inserted into it once it has been placed within the organism. In the case of unicellular organisms the restriction enzyme is first introduced to break apart the DNA and then the plasmid is introduced to create the desired effect. Then the organism can express those genes through further processing of the newly introduced DNA and through mitosis (which is how unicellular organisms reproduce) it can give that gene to its offspring. In the case of multicellular organisms a restriction enzyme and accompanying plasmid must be presented when the organism is just a zygote. This process is how those glow-in-the-dark fish are created and provided that those fish can reproduce they'll also give their traits on to future generations just like single-celled organisms would.
Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!

Why is it that a carrot plant can express a bacterial gene?
Because the genetic code is the same in both organisms.
What is the expression of a gene?
Genes basically express proteins that are the organisms phenotype; the collection of the physiological and behavioral traits of an organism.
Why are arthropods called arthropods?
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
Why are milkweed bugs called arthropods?
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
How do the cock and the hen pass on their characteristics to the chick?
With their genetic material. The chicks have copy, and therefore express a certain amount of the parents traits.
Are girls today having more bisexual relationships than previous generations?
Yes, but only because of the fact that laws and culture have changed to allow bisexual people to express who they are.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
Do obligate anaerobes express superoxide dismutase?
No, obligate anaerobes do not express superoxide dismutase. This is because these organisms do not encounter oxygen in their natural environment and therefore do not need enzymes to detoxify reactive oxygen species like superoxide.
How does biographical characteristics affected by culture?
Biographical characteristics, such as age, gender, and ethnicity, are influenced by cultural norms, beliefs, and practices. Culture shapes how individuals perceive and express these characteristics, impacting behaviors, values, and expectations associated with them. Therefore, biographical characteristics are not only influenced by inherent traits but also by the broader cultural context in which individuals exist.
What is another name for heterozygous?
Another way to express something is heterozygous is to say it has dual alleles. There is a dominant and recessive allele. Alleles determine which traits something will have. Normally this is expressed in a single allele.
Why is a cell the smallest unit of life?
because a single cell can grow completly and could express all the life characteristics and of course it is smallest one
