When the non-sister chromatids of homologous chromosomes exchange segments between them during meiosis is called crossing over.

Genetics is the discipline of science which deals with the study of genes, inheritance, heredity factors, phylogenetic relations, molecular biology, biochemistry, and other advanced knowledge related to genes and inheritance.

Depending on the original character of organisms, fossils found in many forms. For example, the type of material in which it was buried, the chemical action to which it was subjected after its burial.

Thread-like strands growing from the skin of organisms like mammals, humans, or any other animal is called hair. Hair is a keratinized modification of the stratum corneum – the outermost layer of the epidermis.

Freshwater habitats occupy a relatively small part of Earth’s surface but have great importance. They are the economical, cheapest, and convenient source of water for domestic and agricultural usage.

Two German botanists Adolph Engler and Karl Prantl published their classification system. They followed the classification system of Eichler which was a phylogenetic system.

The process of formation of offspring as a result of interbreeding between two animals or plants of the same taxa or can be of different taxa is called hybridization. The organism which is produced as a result of interbreeding is called hybrid.

Plant breeding is used to produce desired traits and changes in plants as a result of their use by humans. Adapting sustainability within agricultural productivity with respect to climate changes, environmental pressures and other such factors strongly depends on the development of resilient, high-yielding crops.

  Monocot Stem Dicot Stem The plants whose seed contains only one embryonic leaf are called monocots. The plants whose seed contains two cotyledons or embryonic leaves are called dicots. Ground tissues are not differentiated into cortex and pith. And composed of parenchyma. Cortex is present. It is composed of collenchyma and parenchyma. The endodermis … Read more Difference between Dicot and Monocot Stems

Phloems are living conducting tissues. They conduct prepared food from leaves to different parts of plants. Also, they are involved in the storage of food and provide mechanical support to plants.
