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 are 3 examples of genotype?
Examples of Genotype:
- Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
- Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
- Lactose intolerance.
How do you describe phenotype and genotype?
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.
How do you express a genotype?
The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype. The dominant allele is capitalized and the recessive allele is lower case.
What are the six genotypes?
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. How are blood types related to the six genotypes?
Is AA a good genotype?
Compatible genotypes for marriage are:
That way you save your future children the worry about genotype compatibility. AA marries an AS. You’ll end up with kids with AA and AS which is good.
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.
Can As marry AA?
It is safe for someone with AS to marry someone with AA genotype. Two sickle cells should not even have a relationship or get married. Individuals with the AA genotype should help you prevent genetic abnormalities by marrying the AS, AC, and SS. Compatible genotypes for marriage are: AA marries an AS.
Which is the best example of a genotype?
Genotype is the set of genes in a DNA which is responsible for a particular trait. Examples of genotype : Eye colour ,Hair colour,Height , Certain diseases,the color stips on the cat.
How many genotypes do humans have?
There are six types of genotype in human beings, and they result in some of the physical characteristics of a person. They are distinguished based on the alleles that a person has.
What is the genotype for gray fur?
ff: 257. Black fur: 257. Grey fur: 757. Genotypes: EE: 1007.
What is the difference between DNA and genotype?
Genotype is the collection of genes responsible for the various genetic traits of a given organism. Genotype refers specifically to the genes, not the traits; that is, the raw information in an organism’s DNA. … Genotype simply means what alleles are carried in a particular organism’s DNA.
