10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 2 2015 (April - June) 'Traditional morphometrics' allows us to decompose morphological variation into its major independent sources, identifying them usually as size and shape. To compare and investigate the properties of size and shape in natural populations of lessThan i greaterThan Drosophila takahashii, lessThan /i greaterThan estimating their seasonal changes, we carried out collections on two different occasions i.e. winter and summer. In the present study the data clearly shows that mean trait values are higher for winter population as compared to summer population MANVENDER SINGH Drosophila takahashii, thorax length, wing length, wing to thorax ratio and body weight etc 1392-1396
