What is the best definition of phenotype quizlet?
Phenotype. An organism’s appearance or other detectable characteristic. Gene. One set of instructions on a strand of DNA for an inherited trait.
Which of the following is the best definition of a phenotype?
phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.
Which one is an example of a phenotype quizlet?
Definition: An allele whose trait (phenotype) is always expressed when present in the genotype. Example: A father has brown eyes with the genotype of HH. A mother has green eyes with the genotype of hh. The son has brown eyes with a genotype of Hh.
Which of the following best summarizes the difference between genotype and phenotype?
Which of the following best summarizes the difference between genotype and phenotype? Genotype refers to the gene alleles that one has, and phenotype refers to the trait that is expressed in response to those alleles.
What is example of phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.
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.
Which of the following is the best definition of genotype quizlet?
The genotype of an organism describes the specific alleles for a particular gene, and the phenotype describes the appearance of the organism associated with the genotype.
Which of the following is the best definition for the term 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.
Which of the following is the best definition of a chromosome?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
What means phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What is the definition of genotype quizlet?
genotype. an organism’s genetic makeup, or allele combinations.
What is tyrosinase quizlet?
Tyrosinase. An enzyme involved with melanin synthesis, which gives the skin its color and also involved with browning of fruits, tubers, and fungi that have been damaged.
Which of the following is a difference between genotypes and phenotypes quizlet?
What is the difference between genotype and phenotype? The phenotype is an organism’s physical appearance, and the genotype is the genetic makeup.
What is the difference between genotype and phenotype?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
Is PP genotype or phenotype?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).
