The recombinant offsprings are normally the offsprings containing a combination of the parents allele, result in a genotype that differs from both parents genotype. The phenotype May be different as well although it is likely that the phenotype could be the same as the parents, as seen in the case of heterozygous dominant having the same phenotype as homozygous dominant.
Oxygen is an element in the sixth group of the periodic table. This means it contains 6 electrons in its valence shell. Therefore, to complete its octet, it will prefer to gain two electrons rather than to donate 6. This is why its valency is -2. The relatively easy to achieve octet makes Oxygen a reactive element.
