Answer:
Methane is a chemical compound with the chemical formula CH4, symbolizing one atom of carbon and four atoms of hydrogen. It is a group 14 hydride and the simplest alkaline, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Methane naturally occurs both below ground and under the seafloor, and is formed by both geological and biological processes. In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water. Methane is important because it can be captured from landfills, can be burned to produce electricity, heat buildings, or power garbage trucks. Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs. In fact, Jordan Dairy Farms in Massachusetts uses a biodigester to turn cow manure into methane gas, which is used for fuel or turned into electricity.

Slight differences in the color of feathers in
birds are the result of mutations. Mutation is process that occurs through a
long period of time. It is a process in which the genes’ structures changes
thus altering the physical characteristics and behaviors of species. This
results into variant forms that may be transmitted to the next generations of
species. Mutation is caused by an alteration of single base units in DNA, or
the deletion, insertion, or rearrangement of larger sections of the genes or
chromosomes. </span>
Answer:
A) 1:2:1
Explanation:
Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles. Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.
In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.
Thus, Option-A is the correct answer
