Zorluk: KolayHuman Morphological and Physiological Variations

The human ABO blood group system is classified as a morphological trait that displays continuous variation across a population.

Cevap: Cevap

Cevap

The statement is false because the ABO blood group system is a physiological trait exhibiting discontinuous variation.
The statement is incorrect because the ABO blood group system represents a physiological trait governed by specific alleles, resulting in discrete phenotypic classes (discontinuous variation) rather than physical structural features along a continuous spectrum.

Adım Adım Çözüm

1
Classify the nature of the trait as morphological or physiological.
ABO blood group involves biochemical antigens present on red blood cells, which makes it a physiological function rather than an anatomical structural trait.
Physiological variations relate to internal body chemistry, metabolism, and organ functioning.
2
Identify whether the distribution pattern is continuous or discontinuous.
Human blood groups fall into four discrete, non-overlapping phenotypes (A, B, AB, and O) without intermediate types.
Discontinuous variations consist of clear-cut qualitative categories determined by genetic inheritance, whereas continuous variations show a smooth spectrum.
