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. Each pair of alleles represents the genotype of a specific gene. ... For example, in sweet pea plants, the gene for flower color has two alleles.
What is a genotype short answer?
The genotype is a set of genes in DNA responsible for unique trait or characteristics while the phenotype is the physical appearance or characteristic of an organism.
What is genotype kid definition?
The entire set of genes, including the specific alleles, found in an organism’s DNA is known as its genotype . So an organism’s genotype is the specific set of instructions it carries around in its cells .
What is genotype with example?
An example of a characteristic determined by a genotype is the petal color in a pea plant . The collection of all genetic possibilities for a single trait are called alleles; two alleles for petal color are purple and white. The genotype is one of three factors that determine phenotype.
What is phenotype in simple words?
“Phenotype” simply refers to an observable trait . “Pheno” simply means “observe” and comes from the same root as the word “phenomenon”. And so it’s an observable type of an organism, and it can refer to anything from a common trait, such as height or hair color, to presence or absence of a disease.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous .
How many genotypes do humans have?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
Can ones genotype change?
Genotype generally remains constant from one environment to another , although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.
What is the function of genotype?
Genotype is the genetic make-up of an individual organism. Your genotype functions as a set of instructions for the growth and development of your body . The word ‘genotype’ is usually used when talking about the genetics of a particular trait (like eye colour).
What are the six genotypes?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
What are 2 examples of genotypes?
- A gene encodes eye color.
- In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father.
- The brown allele is dominant (B), and the blue allele is recessive (b).
What does genotype mean?
What is a genotype? A genotype is the genetic arrangement that makes up the traits that an organism inherited from its parents. Genotype can also mean the entire collection of genes an offspring inherited from its parents .
What is a heterozygous simple definition?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus . A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What is allele simple?
An allele is one of two or more versions of a gene . An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene.
Can AA and AA get married?
AA marries an AA . That’s the best compatible. That way you save your future children the worry about genotype compatibility. ... And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
