Which of the following is the best definition of genotype?
Genotype: The genetic constitution (genome) of a cell, an individual, or an organism. The genotype is distinct from the expressed features, or phenotype, of the cell, individual, or organism. The genotype of a person is that person’s genetic makeup. It can pertain to all genes or to a specific gene.
What is the best definition for genotype quizlet?
Genotype. The combination of genes for one or more specific traits. Heterozygous. A trait that is formed from a recessive and dominant allele.
Which of the following defines genotype?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
What is a genotype quizlet?
genotype. an organism’s genetic makeup, or allele combinations.
Which one is the best genotype?
- Types of Genotype. The genotypes in humans are AA, AS, AC, SS. They refer to the hemoglobin gene constituents on the red blood cells. …
- Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible. …

- AS and AA – normal.
- AS and AS – bad.
- AS and SS – really bad.
- SS and SS – the worst.
Which best defines phenotype?
The phenotype is best defined as the “observable characteristics that result from the expression of genes of an organism, which can largely be modulated by environmental or other conditions” .
What is a genotype example?
A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father. The brown allele is dominant (B), and the blue allele is recessive (b).
Which of the following best describes genotypes and phenotypes which of the following best describes genotypes and phenotypes?
In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”. The dominant trait will be expressed in the phenotypes of individuals with genotypes AA or Aa, while the recessive phenotype will be expressed in individuals with genotype aa.
What is ment by 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. … Human beings have around 20,000 genes in their DNA.
What are 3 examples of genotype?
Examples of Genotype:
- Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
- Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
- Lactose intolerance.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is the correct definition of a genotype and a phenotype?
Genotype versus phenotype. An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment.
What is the definition of an allele quizlet?
An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring. … They are exactly like their parents. It only has one division and that leads to two cells.
