Why is it harder to determine which phenotype a person will have when a trait is controlled by many genes?
When a trait is controlled by many genes (polygenic trait), the interactions and combinations of different gene variations make it difficult to predict the specific phenotype a person will have. The additive effect of multiple genes leads to a wider range of possible phenotypes, making it harder to determine the outcome based solely on genetic information. Additionally, environmental factors can further influence the expression of polygenic traits, adding another layer of complexity to predicting phenotypes.

When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
Why didn't a person with a recessive phenotype have to flip a coin to determine their genotype?
Well, isn't that just a happy little question. You see, if a person shows a recessive phenotype, it means they received two recessive alleles for that trait. So, there's no need to flip a coin because their genotype is already determined. Just like painting a beautiful landscape, genetics can be quite fascinating once you understand the brushstrokes.
What is the name given for the actual physical trait of a person?
The name given for the actual physical trait of a person is "phenotype." This term refers to the observable characteristics of an organism, which are determined by both genetic and environmental factors.
Is the phenotype which determine RH?
The phenotype that determines the Rh factor in blood is based on the presence or absence of the specific protein antigens on the surface of red blood cells. A person can be either Rh positive (having the protein) or Rh negative (lacking the protein) based on their genetic inheritance.
How do you determine genotype?
Either analyzing the DNA sequence (which you probably don't have a lab to do it in) or breeding the organism and use a PUNNET SQUARE to determine if they are purebred. (don't try the breeding experiment on humans.)
When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
Why do chromosomes determine an individuals phenotype?
Chromosomes are made of DNA and protein. DNA is the genetic material that determines the genotype and phenotype of a person. The phenotype is the genes that are expressed and observable. See the related link for further information.
Why is a persons phenotype harder to predict than a persons genotype?
Because peoples appearances changes as their body changes.
Is it possible to determine the genotype of a plant with a dominant phenotype the trait?
NO, because a dominant phenotype could either be homozygous or a heterozygous.so unless you are sure about the genotype of parents we can't determine it...but we can determine the genotype of a person showing reccessive phenotype, as a recessive trait always expresses itself in a homozygous condition..Read more: Is_it_possible_to_determine_the_genotype_of_a_person_showing_a_dominant_phenotype
Is the gene type a person has called their phenotype?
Not exactly. The phenotype is an organism's physical appearance.
When you describe a person's physical characteristics you are describing their?
phenotype
What is the word for the physical characteristics that we can see of a person's trait?
Phenotype
Which term is defined as the way a person acts and looks?
phenotype
What term is defined as the way a person looks or acts?
Phenotype.

How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
What term describes the physical traits of a person?
The term that describes the physical traits of a person is "phenotype," which refers to the observable characteristics or traits of an individual resulting from the interaction of their genetic makeup (genotype) with environmental factors.
