Can you accurately determine a person’s genotype by observing his or her phenotype explain why?

5. Can you accurately determine an organism’s genotype by observing its phenotype? Explain your answer. Although knowing an organism’s genotype would allow one to predict its phenotype, some phenotypic traits can be the result of either homozygous or heterozygous combinations of alleles.

Can you observe a genotype?

Genotype is determined by the makeup of alleles, pairs of genes responsible for particular traits. … Genotype simply means what alleles are carried in a particular organism’s DNA. It can’t be determined by simple observation; it requires biological testing.

Can a person’s genotype be determined by their phenotype quizlet?

A person’s genotype is not determined by their phenotype. The genotype is the genetic makeup of an individual and is the basic instructions for how…

What determines the genotype and phenotype of an individual?


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.

Can a person’s genotype be determined by their phenotype?

No, a person’s genotype cannot be determined solely by their phenotype as many genes in our genome do not get expressed.

How do you determine genotype and phenotype?

Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related.

What determines your person’s genotype?

A genotype is an individual’s collection of genes. … The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules. The expression of the genotype contributes to the individual’s observable traits, called the phenotype.

Can a person’s genotype be determined by their phenotype Why or why not quizlet?

A person has two alleles for each trait. … The phenotype expressed depends on which two alleles a person possessess for a gene and how the two alleles interact. The phenotypes associated with a certain allele can sometimes be dominant, recessive, both or neither. Your genotype determines your phenotype.

Why can’t a person’s genotype be determined by their phenotype?

The genotypes of an individual ca not be determined by the phenotypes expressed by the individual. … Thus phenotypes cannot be used in determining the genetic make of a person as they only give a little information on the alleles responsible for the trait.

Which statement accurately describes how genotypes determine phenotypes?

Which statement accurately describes how genotypes determine phenotypes? genes encode a sequence of amino acids for a particular polypeptide or protein.

How does genotype determine phenotype quizlet microbiology?

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.

What do you understand by phenotype and genotype explain by giving an example?

Genotype can be described as the genetic makeup of an organism. As humans are diploid organisms, they have two alleles at each genetic position, with one allele inherited from each parent. Phenotype refers to the physical properties of an organism, which can be observed with our eyes.
