What is inheritance in biology? On the molecular level, what exactly is a mutation? What does genetic engineering have to do with oncogenes? What is a motif in biology? What is translocation? What is a tetrad? What is hybrid speciation?
What type of evolution is adaptive radiation? What is a tetrad? What is an example of a phenotype? What is polyploid hybrid speciation? What are six patterns of macroevolution? What is a homologous structure example? What are examples of non-heritable traits?
The Earth is home to a wide variety of living beings. It is estimated that about 8.7 million species of living beings are currently on the Earth of which 1.2 million species are known to us. These biotic components have total biomass of about 545.8 gigatons, of which 12.8 % is bacterial ...

NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
tetrad, named so because it has four chromatids total. Within the tetrad, the chromatids of the maternal and paternal chromosomes swap homologous sections of DNA with one another. (I will never forget how my high school biology teacher represented this process with a wacky, arm-waving dance....
January 20th, 2014 at 7:19 pm (Biology,Society) Today I came across a mention of an interesting study, titled: Female Partners of Men Who Use Pornography: Are Honesty and Mutual Use Associated With Relationship Satisfaction? Annoyingly, only the abstract is available; the article costs $39....
(to date) to suggest that spatial navigation skills relate to mathematics abilities, there is well over a century of research linking spatial visualization and mathematics (Davis, 215; Galton,1880; Mix & Cheng,2012). Broadly defined here as the ability to generate, recall, maintain, and ...
With the benefit of insights from molecular biology that were unavailable before the 1960s, it is possible to define inflammation more broadly as a protective response, involving the activation of immune and non-immune cells, in response to an insult such as infection, toxic compounds, damaged ce...
Each bivalent contains four chromatids and is also called tetrad. Pachytene: After completion of synapsis, large recombination nodules appear at intervals on the synaptonemal complex. The non sister chromatids twist around and exchange segments witheach other. ...
