What is an intermediate trait?
a measurable trait in which there is some evidence of the operation of a simple major cause, but in which the variation within the putative categories is such as to cause overlap and hence ambiguity in classification of any particular reading.
What is intermediate expression?
Another example of an intermediate expression may be the pitch of human male voices. The lowest and highest pitches apparently are found in men who are homozygous for this trait (AA and aa), while the intermediate range baritones are heterozygous (Aa).
What does intermediate mean in biology?
An intermediate or reaction intermediate is a substance formed during a middle step of a chemical reaction between reactants and the desired product.
What are intermediate phenotypes?
Definitions. An intermediate phenotype (often referred to as an endophenotype) is a quantitative biological trait that is reliable and reasonably heritable, ie, shows greater prevalence in unaffected relatives of patients than in the general population.
What produces an intermediate phenotype?
This intermediate phenotype is a demonstration of partial or incomplete dominance. When partial dominance occurs, a range of phenotypes is usually observed among the offspring. … Thus, when homozygous red flowers (A1A1) are crossed with homozygous white (A2A2), a variety of pink-shaded phenotypes result.
What is the phenotype of the intermediate offspring?
INTERMEDIATE PHENOTYPE is a phenotype of an offspring expressing a mixture of the phenotypes of the parents.
What phenotype means?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
What is it called when both alleles are expressed?
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. … In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.
