The following points highlight the two main cases of cytoplasmic inheritance. The cases are: 1. Inheritance of Plastids 2. Kappa Particles of Paramoecium. Cytoplasmic Inheritance: Case # 1. Inheritance of Plastids: The cytoplasm of plants bears minute pigments called plastids. Plastids arise from smaller DNA particles of the ovum and multiply by division. During the formation of gamete a plastid [...]
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♂ [...]
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 [...]
