Abstract

Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: Classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counselling. Genes can be the common factor of the qualities of most human inherited traits. Study of human genetics can be useful as it can answer questions about human nature, understand the diseases and development of effective disease treatment and understand genetics of human life. The aim of the study was to see the genetic variation among the students shown in their phenotype. In the present study Survey on Genetical Variation among the Students in AMET University campus, Chennai.

Keywords

Genetical variation; Phenotype; Population genetics

Introduction

This article describes only basic phenotype of genetically variation. This survey was conducted among 100 students of AMET University, Chennai. The aim of the study was to see the genetic variation among the students shown in their phenotype. Normally, due to the certain alleles which dominant than other alleles in the genes, that characteristic of the alleles is expressed in an individual. Therefore, we can see certain phenotype changes in an individual which is unique and makes them appear distinct from another individual.

Methodology

Period of study

This study was conducted in May - 2017.

Data collection

The primary data are those which are collected afresh and for the first time and those happen to be original in character. The major tool has used for collecting data in this study is an interview and questionnaire (Tables 1 and 2).

1. The questions regarding personal data.

2. The questions regarding the identification of Phenotype character.

Gender No. of Respondents
Male 72
Female 28
Total 100

[ ] Toes ranging from big toes longer (upper left)

[ ] Toes ranging from big toe shorter (lower right).

10. Do you have cheek dimples?

[ ] Yes [ ] No

Results and Discussion

In this questionnaire, the first question was what your blood group is most of the students were having ‘B’ blood group (42%), ‘O’ blood group (29%) and ‘A’ and ‘AB’ blood group most of the students are Rh positive (95%) and rest of them Rh negative (5%). The next question was that whether they are able to roll their tongue or not, 80% of students were able to roll their tongue whereas 20% could not.

The most important question was the thumb impression, as we can see in the present days that our thumb impression and finger prints are taken for allotting identity card ‘Aadhar card’ or when travelling in other countries, to identify the person or to create a database having their individual information.

Since our fingerprints or the thumb impression is unique and different from one another most of the students were having circular (70%) thumb impression and arch (30%). 85% of the students have mid-digital hair on their finger while 15% of them do not have. 92% of the students have ears without Darwin’s tubercule while 8% has Darwin’s tubercule. Most of the students have attached ear loop (70%) and 30% have non-attached ear loop.

When the students were asked the question how the pattern of your hair whorl is, 52% of the students were having counter clockwise hair whorl whereas 48% of them have clockwise hair whorl. 48% of them have toes ranging from big toes shorter whereas 52% of them were having toes from lower right and 48% of them were having toes ranging from big toe shorter upper left. 77% of the students have no check dimple while very few students (23%) have check dimples [1-4].

Conclusion

Therefore, as the result majority of the students in our survey are of Rh (+) blood group, they have circular thumb impression, attached ear finger, counter clock wise hair whorl while mostly do not have Darwin’s tubercle and check dimples.
