Alternative versions of a gene?
Alternative versions of a gene are called alleles. Alleles are different forms of a gene that can result in distinct traits or characteristics. These variations in alleles contribute to genetic diversity within a population.
Which is most inclusive A. Allele B. Genotype?
Genotype is more inclusive than allele. Genotype refers to the genetic makeup of an organism, including all alleles present at a particular genetic locus. Allele is a specific form of a gene that can be present at a given locus within an organism's genome.
What is the Trojan gene effect?
The Trojan gene effect refers to a genetic phenomenon where a deleterious gene hitchhikes along with a beneficial gene that spreads through a population. This can result in the deleterious gene becoming more widespread even though it is harmful to the organism.
A gene is said to have multiple alleles if it has more than how many alleles?
A gene is said to have multiple alleles if it has more than two different forms or variants (alleles). This means there are more than two variations of the gene present in a population.
What two factors directly affect the traits of an organism?
Genetic makeup and environmental factors are the two main influences on the traits of an organism. Genetic makeup determines the inherited characteristics, while environmental factors like diet, climate, and social interactions can also shape the expression of those traits.
A transgenic organism that has extra copies of a gene produces more of RNA the that is coded for by the gene?
In a transgenic organism with extra gene copies, there is typically an increase in the production of the corresponding RNA due to the additional gene copies being transcribed. This can lead to an elevated expression level of the gene's product, which could result in observable phenotypic changes in the organism.
What is an organism containing a new gene?
Transgenic - Refers to an organism containing one or more deliberately inserted genes from another species. Examples are bacteria containing the gene for human insulin and plants that contain the gene for a naturally occurring insecticide.
What is meant by gene knockout testing?
Gene knockout testing is a technique used to study the function of a specific gene by inactivating or "knocking out" the gene from an organism's genome. This is typically achieved through genetic engineering methods such as CRISPR-Cas9 to create organisms that lack the target gene. By observing the effects of the gene knockout on the organism, researchers can learn more about the gene's normal function and its role in biological processes.
Name two factors that determine the phenotype of a trait?
genes
What makes up a gene pool of a population?
A gene pool of a population is made up of all the different alleles (versions of a gene) present in the individuals that make up the population. It represents the genetic diversity within a population. The more diverse the gene pool, the greater the genetic variability within the population.
Alternative versions of a gene?
Alternative versions of a gene are called alleles. Alleles are different forms of a gene that can result in distinct traits or characteristics. These variations in alleles contribute to genetic diversity within a population.
Which is most inclusive A. Allele B. Genotype?
Genotype is more inclusive than allele. Genotype refers to the genetic makeup of an organism, including all alleles present at a particular genetic locus. Allele is a specific form of a gene that can be present at a given locus within an organism's genome.
How does the gene for hypokalemic periodic paralysis present?
The gene for hypokalemic PP is present equally in both sexes, but leads to noticeable symptoms more often in men than in women.
What is the Trojan gene effect?
The Trojan gene effect refers to a genetic phenomenon where a deleterious gene hitchhikes along with a beneficial gene that spreads through a population. This can result in the deleterious gene becoming more widespread even though it is harmful to the organism.
A gene is said to have multiple alleles if it has more than how many alleles?
A gene is said to have multiple alleles if it has more than two different forms or variants (alleles). This means there are more than two variations of the gene present in a population.
The stronger of the two traits which show up in an organism is called a?
dominant trait. It is more likely to be expressed in the phenotype of an organism when it is inherited with a recessive trait.
What happens when more than two alternatives for a gene exist?
When more than two alternatives for a gene exist, it is known as multiple alleles. In this scenario, the gene may have more than two allelic forms, each of which can produce a different effect on the phenotype of an organism. This can lead to a wider range of observable traits or variations within a population.
