Law of Independent Assortment: (Third law) is based on inheritance of two genes, i.e. dihybrid cross which states that when two pairs of contrasting traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters. These factors randomly rearrange in the offspring producing both parental and new combination of characters means inheritance of one character does not affect the inheritance of another character and both characters

- Internal budding or endodyogeny is a process of asexual reproduction, favoured by parasites such as Toxoplasma gondii. It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring prior to their separation.
- External budding occurs in hydra where regenerative cells are used for reproduction. In this case, bud develops as an outgrowth due to repeated cell division and when this bud matures, it gets detached from the parent body and develop as full organism

Anamnestic response is the quick and intense response which occurs when an individual encounters a particular antigen for the second time. It is aided by the memory of primary response stored by B-cells. By the administration of a dead or attenuated pathogen in the body of person, a secondary immune response can be ensured due to the presence of memory cells in the body.

Flowers are the reproductive parts of most of the plants. There are two types of flowers based on reproduction. These are bisexual and unisexual flowers.
*A unisexual flower either contains only stamens which is called as male flower or it contains only pistil which is then called as female flower.e.g.Papaya.
Hence, papaya plant bearing male flowers will not have any fruits.

Genetic mapping refers to the determination of the relative positions of genes on a DNA molecule.
following are the contributions of gene maping in Human genome project
1.The gene mapping has made it possible to sequence the whole human genome.
2.Genetic maps have been used to find the exact chromosomal location.
3.On genetic maps distances between markers and genes could be measured.
4. These provided by high resolution genetic maps of the human genome project.
