The representation of the genotypes is as follows:
Homozygous dominant for curly hair (James): CC
Heterozygous dominant for curly hair (wife): Cc
The curly or straight hairs are the phenotypes and CC or Cc is the genotype of parental alleles.
When the first child is born which means the F1 generation, the type of hair the child will have can be predicted by punnet squares.
The Punnet squares have been shown in the image.
From the above punnet squares, two out of four probable phenotype or genotype of curly hair is 2/4 = 1/2 or 50%, have CC as their genotype and are homozygous dominant for curly hairs.
Answer:
Explanation:
Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.
Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Part of the radiation from these elements consists of alpha particles, which form the nuclei of helium atoms. ... Helium can also be produced by liquefying air and separating the component gases
When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is often used in order to recover the helium content. Once the helium has been separated from the natural gas, it undergoes further refining to bring it to 99.99+% purity for commercial use.
