Law of Segregation – Biology Definition Question: What is the law of segregation? Answer: It is also called the first law of inheritance. The law of segregation states that: ‘‘The two copies of each genetic factor segregate during the development of gametes, to ensure that each parent’s...
such as the color of the flowers, the color of the seeds, the height of the pea plant, etc. were inherited. He performed crosses, mating offspring to parents, to test one trait at a time. To explain the law of independent segregation, we will use the color of ...
PIWI-interacting RNAs (piRNAs) support the germline by suppressing retrotransposons. Studies of the pathway in mice have strongly shaped the view that mammalian piRNAs are essential for male but not for female fertility. Here, we report that the role of the piRNA pathway substantially differs in g...
Thus, narrow definitions have become inappropriate or inaccurate, and a more encompassing definition is required in order to describe this complex cell biological programme. Fig. 2: Growth of the primary literature in EMT. The first experimental analysis of epithelial–mesenchymal transition (EMT) in...
Without this chromosomal alignment, it is not possible to carry out accurate segregation of chromosomes during cell division. Figure 5: Notice the alignment of duplicated chromosomes (consisting of sister chromatids) at the metaphase plate. Image Credit: Chromosoma (Reference-2) Genetic Recombination...
Many cell biological facts that can be found in dedicated scientific textbooks are based on findings originally made in humans and/or other mammals, includ
some viruses for their plant hosts, however, have been detailed by fresh information in recent years. According to one definition, viruses interact mutually with plant cellular systems, providing some abiotic stress protection for plants (González et al.2020). One of the early research in this ...

However, few cancer-associated mutations in these or other mitotic regulators have been described thus far and many of these molecules do not fit into the classical definition of 'oncogenes' or 'tumor suppressor genes'. In some cases, both over-expression and decreased expression of these genes...
On the one hand, global functional connectivity is crucial for the effective segregation and integration of information processing in the brain. Neural communication that underlies global functional connectivity is largely dependent on the integrity of these essential cortical components. On the other hand...
