Zorluk: OrtaHuman Morphological and Physiological Variations

Match each human genetic trait on the left with its correct classification of variation on the right.

  • ABO blood group systemDiscontinuous physiological trait determined by multiple alleles
  • Human height distributionContinuous morphological trait controlled by polygenes and environmental factors
  • Fingerprint ridge patternDiscontinuous morphological trait that is distinct and unaffected by environment
  • Ability to taste phenylthiocarbamide (PTC)Discontinuous physiological trait dividing individuals into distinct taster and non-taster categories

Cevap

The ABO blood group system matches discontinuous physiological trait determined by multiple alleles; Human height distribution matches continuous morphological trait controlled by polygenes and environmental factors; Fingerprint ridge pattern matches discontinuous morphological trait that is distinct and unaffected by environment; Ability to taste PTC matches discontinuous physiological trait dividing individuals into distinct taster and non-taster categories.
Each trait is accurately matched according to its classification as either anatomical/structural (morphological) or biochemical/functional (physiological), alongside its pattern of inheritance (continuous spectrum vs. discrete discontinuous categories).

Adım Adım Çözüm

1
Distinguish between morphological traits (physical body structures) and physiological traits (biochemical and functional characteristics).
Height and fingerprints are morphological features; blood group and PTC tasting ability are physiological features.
Morphological traits relate to form and structure, whereas physiological traits relate to chemical function and biological mechanisms.
2
Categorize each feature as displaying continuous (gradient/range) or discontinuous (discrete non-overlapping groups) variation.
Height varies continuously across a spectrum; blood groups, fingerprints, and PTC tasting divide individuals into distinct, non-overlapping categories.
Continuous variation involves polygenic inheritance influenced by environmental factors, while discontinuous variation is typically controlled by one or a few genes with little to no environmental modification.
3
Pair each specified human feature on the left with its full description on the right.
All left items are accurately paired with their corresponding variation profile.
This confirms mastery of human morphological vs. physiological and continuous vs. discontinuous variation concepts.
