What determines an organism’s phenotype?

What determines an organism’s phenotype quizlet?

Phenotype. The visible or measurable expression of the genetic make-up of an organism’s structure and/or functioning. Genotype. The underlying genetic make-up that determines an organism’s phenotype.

What is the best way to determine the phenotype of an organism?

An organism’s genetic makeup is called its genotype, and it reflects all of the alleles, or forms of the gene, that are carried by the organism. Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

What determines the genotype of a cell quizlet?

Genotype (Pp): ACTUAL alleles inside DNA w/in their cells. Phenotype (Purple): EXPRESSED/OBSERVABLE traits of an organism; determined by its genetic makeup. You just studied 48 terms!

How does the phenotype depend on its genes?

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. … For example, differences in the genotypes can produce different phenotypes.

What environmental factors affect phenotype?

Environment Can Impact Phenotype

Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.

What does an organism’s phenotype describe Brainly?

Explanation: 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.

Where one can determine the genotype and phenotype?

The test cross is another fundamental tool devised by Gregor Mendel. In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).

How does genotype determine phenotype quizlet?

How does the genotype of an organism determine its phenotype? By specifying what kinds of RNA and which structural, enzymatic, and regulatory protein molecules are produced. -Polypeptides determine phenotype by acting as structural, enzymatic, and regulatory proteins.
