What is discontinuous variation
Discontinuous variation refers to things like eye colour or blood group, which have a limited number of possible values. In other words, a person's blood can be A, B, AB or O, but it can't be anything in between.
What is discontinuous variation identified
discontinuous variation (qualitative variation) Clearly defined differences in a characteristic that can be observed in a population. Characteristics that are determined by different alleles at a single locus show discontinuous variation, e.g. garden peas are either wrinkled or smooth. Compare continuous variation.
What are the 2 types of variation
variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
Is eye colour continuous or discontinuous variation
Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.
Why is there continuous variation
Two reasons for continuous variation: Mendel had noticed in his original paper in 1865 that multifactorial inheritance (i.e. the character is influenced by many genes) can generate a continuous variation. Characters influenced by many genes are called polygenic characters.
IS fingerprint continuous or discontinuous variation
Fingerprint: This is a type of discontinuous variation whereby each human being has a fingerprint that is specific to that person. This is due to slight variation in the main groups of the fingerprints.Jun 17, 2016
What is discontinuous trait
Definitions. Discontinuous traits – traits with only a few possible phenotypes that fall into discrete classes; phenotype is controlled by one or only a few genes (ex.: tall or short pea plants; red, pink or white snapdragon flowers)
Is weight continuous or discontinuous variation
For any species, a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: height. weight.
Is hair color continuous variation
Continuous variations are differences in characteristics that have a range of possible variations, such as height, shoe size, hand span, skin color, hair color, etc. Discrete variations are differences in characteristics that have a definite form, with a limited number of possibilities.
What is an example of discrete variation
Discrete variation is either/or and is often caused by the presence or absence of a small number if genes. For example, our ability to "roll" our tongues is determined by just one gene. We can all either roll our tongue or not – there's nothing in between.
Why is it called discontinuous variation
noun Biology. variation in phenotypic traits in which types are grouped into discrete categories with few or no intermediate phenotypes. Compare continuous variation.
What is discontinuous variation explain with EGS
Solution : In discontinuous variation, two or more allelic forms of one or two major genes control the characteristic of an individual within a population. These characteristed show a limited form of variation, which are generally determined by inheritance factors.Apr 17, 2022
What is discontinuous variation Igcse biology
Discontinuous Variation is when there are distinct differences for a characteristic. For example, people are either blood group A, B, AB or O; are either male or female; can either roll their tongue or not – there are no 'inbetweens'
What does the word discontinuous mean
Definition of discontinuous
1a(1) : not continuous a discontinuous series of events. (2) : not continued : discrete discontinuous features of terrain. b : lacking sequence or coherence. 2 : having one or more mathematical discontinuities —used of a variable or a function.May 13, 2022
What is a discontinuous gene
A gene in which the coding information is split up between two or more strand lengths called EXONS, which are separated from each other by non-coding sections called INTRONS. Many genes are discontinuous.
What is another name for discontinuous variation
classification of variation
A discontinuous variation with several classes, none of which is very small, is known as a polymorphic variation.
Who identified discontinuous variation
' These differences or diversity in structure within any species was first recognized by Darwin and Wallace. If a study is conducted on one large population, two forms of variation could be seen as continuous variation and discontinuous variation.Aug 9, 2017
What is discontinuous variation caused by
Discontinuous variation is usually caused by one gene and is not affected by the environment.
