In a group of dogs, some individuals have short fur and others have long fur. In this group,
the gene for the fur length trait has two alleles. The allele F is for short fur, and the allele f is
for long fur.
Clue, a dog from this group, has long fur. Clue has two alleles for long fur.
Based on this information, what is Clue's genotype for the fur length gene?

A) short fur
Bl long fur
C) FF
D) ff

D) ff

Explanation: Clue's genotype for fur length gene is ff. From the information given above, the allele for long fur is f and Clue has two alleles for long fur.

Since long fur allele is f and Clue has two long fur alleles, therefore clue's genotype for long fur is ff.

A genotype is a pair of gene that controls a particular trait. A gene appear in different forms known as alleles. Long fur trait in Clue is controlled by a pair of gene ff.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
