A clastic rock composed of sand-sized grains derived from the physical weathering of granite and containing a sizable proportion of feldspar is termed as arkose. It is a sedimentary rock that has a composition of at least 25% feldspar. It is a type of sandstone that has a coarse texture and is commonly in gray or pink in color. The most important minerals in arkose are feldspar and quartz. And, it is quartz that is dominant in composition. This rock is formed from weathering of metamorphic or igneous rock that are rich in feldspar. They are to be quickly deposited into cold environments so as to avoid chemical weathering.

For a heterozygote, the production of the protein by the DOMINANT allele compensates for the production of a non-functional protein by the RECESSIVE allele. It is classical genetics.
<h3>Alleles and dominance</h3>
An allele is a gene variant, diploid individuals inherit two different alleles for a given gene locus.
A homo-zygous individual has the same alleles, whereas a heterozygous individual has two different alleles for a given gene locus.
Dominance occurs when the dominant allele completely masks the expression of the recessive allele.

<span>The model of modern human origins depends, in part, on the archaic interbreeding of Neanderthals and Homo Sapiens (not the modern Homo Sapiens Sapiens, which is what human beings are to this day.) From this coupling rose a species, us, which was tough and less impervious to cold, a quality gained from the Neanderthals, and a more robust brain size, a quality obtained from Homo Sapiens.</span>
