2. What are morphological traits ?
• Morphology traits are a special structural feature in an
organisms that is genetically inherited from parents to
offspring.(1)
• Morphogenetic traits help to distinguish among organism of
the same species and are a source of variation.(2)
• Morphogenetic traits are observable characters inherited by
individuals from their parents in autosomal dominant or
recessive manner and expressed differently among
populations.(2)
• . Thus, Morphological traits it is useful in evaluating and
analyzing the evolutionary forces and classification.(3)

3. Morphogenetic traits in human.
• Most morphogenetic traits are usually
inherited in Mendelian fashion as a result of
single gene as either autosomal dominant or
autosomal recessive whereas some traits such
as skin colour, hair colour, ear lobes, shape of
hair, Bent little finger, Rolling of tongue, eyes
colour and dimple on cheek and thin are
polygenic, being affected by more than one
gene.(4)

4. Objective
• To evaluate the distribution and inheritance patterns of some
morphogenetic traits; and to determine the association
between the selected morphogenetic traits among the
students.

5. STEPS TO DETERMINE TRAITS
AMONG STUDENTS.

6. 1.MATERIALS AND METHOD.
• 1.1 POPULATION OF STUDY
• The study was carried out in a heterogenous
population of students admitted during the
2018/2022 academic session for various
programmes in the Computer programming,
Engineering, Faculties of Science, Clinical
Sciences, Basic Medical Sciences and Social
Sciences. A total of 500 students between the
ages of 16 and 26 were randomly selected for the
study.

7. • 1.2 Participants recruitment
• The study employed cross-sectional sampling
method.
• Respondents sampled were not related by
blood and gave informed consent to
participate in the study. Those who did not
consent to the study were not included.

8. • 1.3 Data collection and analysis
• All participants were observed for presence or
absence of dimples on cheek and chin, ability to
roll the tongue or not, presence of free or
attached earlobe, bent or straight little finger,
different color of eyes, different types of hair
colour different shapes of hairs. Observed
differences in individuals were assigned
dominant and recessive respectively according
to the work.
