Which of the following is the definition of phenotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Whats the definition of phenotypes?

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.

Which of the following is the best definition of the term phenotype?

1 : the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical expression of one or more genes Considering that modern maize is a tetraploid, it is remarkable how many single gene mutations cause profound changes in phenotype.—

What is the best definition for phenotype quizlet?

What is the best definition for phenotype? The outward appearance of a trait resulting from the interaction of genes and the environment.

What’s my phenotype and genotype?

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. A change in the environment also can affect the phenotype. …

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.

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.

What is homozygous quizlet?

homozygous. an organism that has two identical alleles for a trait (purebread) phenotype.

What is the third phenotype?

The intermediate trait appearance in between the phenotypes of homozygous traits in the heterozygote is called incomplete dominance. The formation of a third phenotype specifically with traits that results from the combination of parent alleles is known as incomplete dominance or.

What are the phenotypes of the offspring?

Eye color, hair color, pod shape, and flower position are all examples of phenotypes. In this example, it asked you to do a cross between two parents who were homozygous dominant for eye color. Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene.

What is a phenotypic ratio example?

Genotypes can be used to find the phenotypes of an organisms’ offspring through a test cross and in turn, acquire the phenotypic ratio. For instance, if a red bug and a blue bug mate, their offspring could be red, blue, or purple (a mixture of both colors).
