<th>Basis for Comparison</th> <th>Incomplete Dominance</th> <th>Co-Dominance</th>
Meaning The condition when neither of the alleles is dominant, rather combine and display a new trait by mixing of the two alleles is called as Incomplete Dominance. The condition when both the alleles of a gene are dominant, and the traits are equally expressed, called as Co-Dominance.
Dominancy Neither of both the allele is dominant and give a new trait. Both the alleles are fully dominant.
Example Snapdragon, Mirabilis Jalapa. Roan character in cattle, A and B blood group in human.
Effect Though both the allele blend their effect, one of the two is more noticeable. Here both the alleles equally blend and show their equal effects.

Homology refers to the evolutionary phenomena in which organisms exhibit similarity in their structure and are said to belong to the same origin or having the common ancestry but they exhibit difference in their function.

The bones of the forelimbs of whale, bat, cheetah and man are similar in structure this indicates the fact that these structures are homologous and their functions are different that is bones in forelimbs of whales helps them to flip and swim in water, in bats helps them to fly, in cheetah and humans help them to move and feed, write respectively.

Length of DNA can be calculated by simply multiplying the total number of base pair with distance between two consecutive bp, i.e. 6.6 {tex}\times{/tex} 109bp {tex}\times{/tex} 0.34 {tex}\times{/tex} 10-9m/bp.
It comes about 2.2 m (0.34{tex}\times{/tex}10-9 m is the distance between two consecutive base pairs).

Base pairs refer to the sets of hydrogen-linked nucleobases that make up nucleic acids DNA and RNA. They were first described by Dr. Francis Crick and Dr. James Watson who are best known for discovering the helical, “twist around,” structure of DNA (1953). At this time, DNA was also identified as the source of transferring material that takes place during cell division. In their model, Watson and Crick predicted that the two strands of DNA are able to intertwine with the help of rule-abiding hydrogen bonds.

The antibiotics are substances produced by the natural metabolic processes of spore-forming aerobic bacteria and fungi as their natural defense against other microorganisms. Among bacteria and fungi, bacterial genera outnumber the fungal genera in the production of antibiotics. The highest numbers of antibiotics are derived from bacterial genera <i>Streptomyces</i> and <i>Bacillus</i> and fungal genera <i>Penicillium</i> and <i>Cephalosporium</i>. These antibiotics are used to control the disease-causing bacteria.

All Cyanobacteria are autotrophs, having the capacity to synthesize organic carbon by reduction of inorganic carbon. Most cyanobacteria use for this synthesis light energy (photosynthesis), but a few species in specialized dark environments use instead chemical energy (chemosynthesis). Cyanobacteria are photoautotrophic bacteria obtaining their carbon and energy by photosynthesis, while heterotrophic bacteria rely on organic compounds as their carbon and energy source.

Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body.

Lead is found in lead-based paints, including paint on the walls of old houses and toys. It is also found in:

  • art supplies
  • contaminated dust
  • gasoline products sold outside of the United States and Canada

Lead poisoning usually occurs over a period of months or years. It can cause severe mental and physical impairment. Young children are most vulnerable.

Children get lead in their bodies by putting the lead-containing objects in their mouths. Touching the lead and then putting their fingers in their mouths may also poison them. Lead is more harmful to children because their brains and nervous systems are still developing.

Lead poisoning can be treated, but any damage caused cannot be reversed.
