A genotype is a scoring of the kind of version gift at a given area (i.e., a locus) inside the genome. it could be represented by way of symbols. as an example, BB, Bb, bb may be used to represent a given variation in a gene.
In a huge sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's entire set of genes. In a extra narrow feel, the term may be used to refer to the alleles, or variant types of a gene, which might be carried by way of an organism.

Water would quickly evaporate if the opening was left open. Fortunately, guard cells are what open and close the stomata. This enables management of water loss and transpiration. In hot weather, guard cells close the stoma.
The guard cells and stoma at the base of the leaf blade serve what purposes?The stomata (stoma = "hole") in leaves are the entry and exit points for carbon dioxide and oxygen, which cannot pass through the cuticle. Stomata are opened and closed by guard cells. Plants lose water vapor to the atmosphere when their stomata are open, allowing gases to pass through the leaf surface.
When the environment is unfavorable, some plants reduce water loss by closing their stomata. In order to maintain a stable water balance in the leaf, plants frequently close or partially close their stomata when the humidity is low. This is because low humidity increases the likelihood that water will evaporate quickly from the surface of leaves.
