Answer:
10.2 cM
Explanation:
Given,
pure breeding parent 1 : BBgg = brown coat and pink eyes
pure breeding parent 2 : bbGG = white coat and green eyes
BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )
When F1 progeny is test crossed with white coat and pink eyes hamster:
BbGg X BbGg = F2 =
brown, pink eyes = 99 = parental
white, green eyes = 103 = parental
brown, green eyes = 12 = recombinant
white, pink eyes = 11 = recombinant
Recombination frequency =
(total number of recombinants / total progeny ) * 100
= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %
1 % recombination frequency = 1 cM distance between genes
Hence, the distance between B and G gene is 10.2 cM
Finish. The work is done then the work is finish.
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
Answer: Plaques
Explanation:It’s used to describe the accumulation of different kinds of deposits on the teeth, which promote dental caries.
