What term is given to the total genetic information carried by all members of a population group of answer choices?
The total genetic information available in a population is called the gene pool.
What is the term for all genes in a population?
The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.
What is the term for the total genetic information in a population quizlet?
The total genetic information available in a population is called the: gene pool.
What is the actual genetic information carried by an individual called?
Actual genetic information carried by an individual is called: Phenotype. An expression of genes; one's appearance. You just studied 52 terms!
Which is a phenotype?
Phenotype refers to an individual's observable traits, such as height, eye color and blood type. A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.
What is gene pool in genetics?
A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species. A large gene pool has extensive genomic diversity and is better able to withstand environmental challenges.
What is a term genome?
Listen to pronunciation. (JEE-nome) The complete set of DNA (genetic material) in an organism. In people, almost every cell in the body contains a complete copy of the genome.
What do mean by genome?
A genome is the complete set of genetic information in an organism. It provides all of the information the organism requires to function. In living organisms, the genome is stored in long molecules of DNA called chromosomes.
What does the term genetic drift mean?
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.
What is gene pool concept?
A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species. A large gene pool has extensive genomic diversity and is better able to withstand environmental challenges.
What allele means?
Listen to pronunciation. (uh-LEEL) One of two or more DNA sequences occurring at a particular gene locus. Typically one allele (“normal” DNA sequence) is common, and other alleles (mutations) are rare.
What is the actual genetic information carried by an individual called quizlet?
Genetic information is carried on double strands of DNA known as chromosomes.
What does genotype mean?
In one sense, the term “genotype”—like the term “genome”—refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.
What is an AS genotype?
For a child to be born with the condition, both parents must carry a sickle-cell gene, (known medically as AS genotype), which is passed from one generation to the next. If someone with a trait marries another person with it, there's a higher chance that their child will be born with the disease.
What is a gene pool in a population?
A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species. A large gene pool has extensive genomic diversity and is better able to withstand environmental challenges.
Which of the following terms refers to the genetic variety within all populations of a single species?
Biodiversity is a complex term that includes not only the variety of different animals (species diversity) but also the difference between animals of the same species (genetic diversity) and between ecosystems (ecosystem diversity).
What is genetic information in biology?
Genetic information. The heritable biological information coded in the nucleotide sequences of dna or rna (certain viruses), such as in the chromosomes or in plasmids.
What is the definition of a proteome?
Listen to pronunciation. (PROH-tee-ome) The complete set of proteins made by an organism. Proteins are made in different amounts and at different times, depending on how they work, when they are needed, and how they interact with other proteins inside cells.
What karyotype means?
A karyotype is an individual's complete set of chromosomes. The term also refers to a laboratory-produced image of a person's chromosomes isolated from an individual cell and arranged in numerical order. A karyotype may be used to look for abnormalities in chromosome number or structure.
What is the other name of genetic drift?
genetic drift, also called genetic sampling error or Sewall Wright effect, a change in the gene pool of a small population that takes place strictly by chance.
What is genetic drift quizlet?
Genetic drift. Any random change to the allele frequency of a population due to a chance event.
Whats the meaning of genotype?
A genotype is the genetic arrangement that makes up the traits that an organism inherited from its parents. Genotype can also mean the entire collection of genes an offspring inherited from its parents.
What is another word for allele?
allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome.
What is a gene locus quizlet?
A gene locus is the location of a gene on a chromosome. Define alleles: Understanding: The various specific forms of a gene are alleles. Alleles are alternative forms of a gene that code for the different variations of a specific characteristic.
What are loci in biology?
(LOH-kus) The physical site or location of a specific gene on a chromosome.
What is a phenotype and genotype?
A person's genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.
What is a karyotype in genetics?
A karyotype test looks at the size, shape, and number of your chromosomes. Chromosomes are the parts of your cells that contain your genes. Genes are parts of DNA passed down from your mother and father. They carry information that determines your unique traits, such as height and eye color.
What is allele in biology?
Listen to pronunciation. (uh-LEEL) One of two or more DNA sequences occurring at a particular gene locus. Typically one allele (“normal” DNA sequence) is common, and other alleles (mutations) are rare.
What does the term genetic diversity refers to?
Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments.
What is genetic diversity in biodiversity?
Genetic diversity is the biological variation that occurs within species. It makes it possible for species to adapt when the environment changes. Genetic diversity is particularly important under rapid environmental change, such as in the Baltic Sea.
