Abstract

Selection is continuously occurring on the living beings and the fittest who are able to reproduce will survive. To measure this selection, the data from 954 women was obtained who belong to different ethnic groups of Gujarat and Maharashtra and various index and components were computed using Crow`s Index and Johnston and Kensinger`s Index. The Crow`s total index value was found to be 0.539. The mortality component was found to be 0.130 and fertility component was found to be 0.363. The contribution of fertility component was greater than the mortality component according to Crow`s Index. Value of total selection index computed using Johnston and Kensinger`s Index is 0.639. The index of selection due to pre‐natal mortality and post‐natal mortality was observed to be 0.064 and 0.130 respectively. Therefore, it is found that among coastal populations of Gujarat and Maharashtra the selection trend is more due to fertility component than mortality component.

Section 2 – Scope.

  1. License grant.
    1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:
      1. reproduce and Share the Licensed Material, in whole or in part; and
      2. produce, reproduce, and Share Adapted Material.

    4. Media and formats; technical modifications allowed.

The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material.

    6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

  2. Other rights.

    1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.
    2. Patent and trademark rights are not licensed under this Public License.
    3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties.

  1. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database;
  2. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.
  1. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

    2. upon express reinstatement by the Licensor.
    For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.
  3. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.
