Discontinuous variation in blood groups is primarily caused by genetic differences in alleles inherited from parents. Each blood group (A, B, AB, O) is determined by specific combinations of alleles for the ABO gene, which can express distinct antigens on the surface of red blood cells. This variation is discrete, meaning individuals fall into distinct categories without intermediate phenotypes, contrasting with continuous traits like height. Environmental factors do not influence blood group variation, as it is solely determined by genetics.
What else can I help you with?
Are blood groups discontinuous data?
Yes, blood groups are considered discontinuous data because they fall into distinct categories that do not overlap. Each blood group (e.g., A, B, AB, O) represents a specific classification based on the presence or absence of certain antigens on the surface of red blood cells. This categorical nature means that individuals cannot belong to more than one blood group at the same time, making it a clear example of discontinuous data.
Which is an example of continuous variation in hunams?
blood group
What is the difference between discontinuous and continuous variation?
Continuous theory of matter says that matter comes in long continuous sheets,it never breaks while the discontinuous theory of matter assumes that matter comes in smaller packets and the reason why matter looks continuous is because we can't magnify it enough to see the small packets of matter. Continuous variation or continuous matter is gradual, something that is not so clear cut. For example, height can vary amongst population and there are many different heights. Discontinuous variation or matter is where you are either in one category or the other, but never in between. Examples of this are: Blood group - you are either O, A, AB, ABO but never anything in between. Another example would be tongue rolling - you can either tongue roll or you can't.
What causes blood to lyse?
Absorbing heam group of heamoglobin
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
What varies in one nucleotide to another in DNA?
The nitrogenous base is what causes variation. The deoxyribose and phosphate group are the same on all nucleotides.
In DNA what varies from one nucleotide to another.?
The nitrogenous base is what causes variation. The deoxyribose and phosphate group are the same on all nucleotides.
What is a variation of a language spoken by a particular group of people?
Dialect is the variation of language from a particular group
What is the meaning of A1 blood group?
The A1 blood group is a subtype of the ABO blood group system, specifically referring to individuals with type A blood who have a specific genetic variation. In the ABO system, the presence of A antigens on red blood cells categorizes blood as type A, while the A1 subgroup is characterized by a stronger expression of these antigens compared to the A2 subgroup. This distinction can have implications in blood transfusions and organ transplants, as compatibility is critical for successful outcomes.
What is variation in a?
triplets happen when 1 agg splits into 3 and triplets form, they either look the same or not the same but they have tha same blood group.
What is a variation in triplets?
triplets happen when 1 agg splits into 3 and triplets form, they either look the same or not the same but they have tha same blood group.
How is variation related to?
The more variation there is in a group of specimens, the more evolution can occur between them.
