genetic material comes from two parents of the same species
genetic material comes from two parents of different species
genetic material comes from many parents
उत्तर
genetic material comes from two parents of the same species
Explanation -
During sexual reproduction, gametes produced through meiosis from two different individuals of the same species fuse to form a new individual. These gametes have genetic material or DNA copies with variations. Fusion of gametes combines their DNAs with variations. So, the resulting offspring has new combinations of variants.

| The most obvious outcome of the reproduction process is the generation of individuals of similar design, but in sexual reproduction they may not be exactly alike. The resemblances as well as differences are marked. The rules of heredity determine the process by which traits and characteristics are reliably inherited. Many experiments have been done to study the rules of inheritance. |
