What observation is explained by the law of independent assortment? recessive trait forms are always hidden in the f 1 generation. each pair of chromosomes separates on its own during meiosis. dominant trait forms are always displayed in the f 1 generation. homologous chromosomes cluster in tetrads during meiosis.

Correct B). Each pair of chromosomes separates on its own during meiosis.  

The Law of independent assortment states that a pair of alleles separates independently during the formation of gametes. It means that trait is transferred to the offspring independently of another gene.

When a cell divides during the meiosis, chromosomes are distributed randomly during the anaphase-1 of meiosis, which results in segregation and separation of genes independently of each other. And it leads to the formation of unique formation of chromosomes in the gametes.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
