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.
What are the 3 types of phenotypes?
With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
What is phenotype and genotype with examples?
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.
What are the 6 blood type 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.
What is an example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What genotype is blonde hair?
Recessive alleles are represented with lowercase letters. b, for blonde hair, is a recessive allele. This means that someone who has a genotype of “bb” will have blonde hair.
How many phenotypes can be expressed?
There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.
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.
