Learn about the difference between Nuclear Traits and Extra-Nuclear Traits. 1. Reciprocal Differences: Differences in the results of reciprocal crosses would suggest a deviation from the pattern of Mendelian autosomal gene transmission. According to Mendelian inheritance, the chromosome complement in male and female gametes obtained from the same species would be similar; reciprocal crosses should give same results (♀A x♂ [...]
The following points highlight the top two types of Cytoplasmic Organellar Inheritance. The types are: 1. Plastid Inheritance 2. Mitochondrial Inheritance. Cytoplasmic Organellar Inheritance: Type # 1. Plastid Inheritance: The most established cases of true cytoplasmic inheritance are those that involve plastids, which are minute cytoplasmic organelles in plant cells. Most important of these plastids are chloroplastids carrying green pigment, [...]
In this article we will discuss about:- 1. Subject Matter of Cytoplasmic Inheritance 2. Maternal Effects of Cytoplasmic Inheritance 3. Infective Particles. Subject Matter of Cytoplasmic Inheritance: The inheritance of characters controlled by the genes is principally related to the chromosomes of the nucleus. These genes, which earlier designated as factors by Mendel, follow a distinct pattern of inheritance as [...]
