Is it possible for two parents who have the same phenotype look the same to have different genotypes?

Can organisms with different genotypes have the same phenotypes? … The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).

Do both parents have the same phenotype?

In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele. … Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive.

Can there be two people with identical phenotypes?

Everyone has a unique phenotype — even identical twins. For most people, your genotype is unique, and even if you’re an identical twin you may be subject to different environmental influences and experiences than your twin; as a result, your phenotype will be different.

How can two offspring from the same parents have different phenotypes?

Answer: Genes come in different varieties, called alleles. … However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism’s offspring and expressed in a later generation.

What traits are genetic?

Most traits are determined by more than one gene. For example, skin color and height are determined by many genes. Some phenotypes however, are determined by a single gene.

What is the difference between phenotype and phenotyping?

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.

When geneticists look at genotype What are they really studying?

Mendel’s hereditary “factors” are variants of genes called alleles. Genotype describes the combination of alleles that an individual has for a certain gene, while phenotype describes the traits that you can see.

What do you inherit from each parent?

One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.

Is personality a phenotype?

Personality phenotypes are extremely variable. Minor variations in measures and samples influence the number and contents of factors identified. Confidence in any structure would, therefore, be increased with evidence that the phenotypic structure reflects an underlying genetic architecture.

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.
