A number of plants develop unique adaptive modifications to overcome the various environmental stress. These modifications include alteration of gross morphological features as well as anatomical structures. Some examples of anatomical changes are given: A. Loaf Anatomy of Nerium sp. (Fig. 8.1): The T.S. view of Nerium leaf shows the following layers of tissues: 1. Epidermis: Both upper and lower [...]
The following points highlight the top four examples of cytoplasmic inheritance in eukaryotes. The examples are: 1. Sigma Virus of Drosophila 2. Milk Factor in Mouse 3. Maternal Sex Ratio Condition in Drosophila 4. Cytoplasmic Male Sterility (CMS). Cytoplasmic Inheritance: Example # 1. Sigma Virus of Drosophila: Normally, Drosophila is anesthetized by CO2 without any after effect. But certain strains [...]
In this article we will discuss about the examples of incomplete dominance in genetics. Mendel's law of dominance states that out of a pair of allelomorphic, contrasting or alternative characters one is dominant and the other recessive. For example, when Mendel crossed a true breeding red flowered plant with a true breeding white flowered one, the offspring produced was found [...]
